                  IT TOOK YEARS TO REFRAME 9-11

The American Conservative           December 6, 2004

Weaker Than We Think

9/11 may join the Trojan Horse & Pearl Harbor among


stratagem so surprising that their success precludes their repetition.

Russell Seitz


On Oct. 18, President Bush asked if today we are still living in the ’90s, “in the mirage of safety that was actually a time of gathering threats.”

The Weekly Standard takes this to mean “a need to fundamentally change the political culture of the Middle East” lest, as Bush declared, 

“anger and resentment grow for more decades … feeding more terrorism until radicals without conscience gain the weapons to kill without limit.”

This is Cold War rhetoric warmed over. No longer do we face an Evil Empire bristling with ICBMs behind its Iron Curtain but a region without strategic weapons and already twice invaded. Salafist fanaticism is a worthy successor to Marxist zeal when it comes to malevolence, but policy must consider the capacity for action, not intent alone. To judge by action, terrorism indeed took advantage of our at best sporadic vigilance and summoned its resources in the ’90s much as the president’s speech observed. But how does its actual capacity for evildoing compare with the sum of our fears?

In a War on Terror, knowing the enemy’s numbers is vital. London’s International Institute for Strategic Studies reckons Osama bin Laden has recruited 18,000 since 9/11, while some DOD officials think he’s down to his last 3,000 men. 

Others say that numbers do not matter: it took only 25 to fill the Trojan Horse, and a few thousand National Socialists and Bolsheviks gave lie to Lenin’s dictated identity of quantity and quality.

Today, we have seen the enemy and he has, at most, one division under arms, making it hard to believe a replay of the Thirty Years War is in the offing. Many horrors of the 20th century stemmed from the metastasis of small cadres, but the exponential growth of totalitarian movements remains an historical rarity. Few last long enough to outgrow their infamy. At the margin, 9/11 could join the Trojan Horse and Pearl Harbor among stratagems so uniquely surprising that their very success precludes their repetition. 

It takes singular ingenuity to achieve stunning surprise. The ruse that broke a ten-year stalemate and burned the topless towers of Ilium came from Odysseus’ cunning mind, not Agamemnon’s planning staff. After the failed 1993 attack on the World Trade Center, Mohammad Atta applied himself to calculating the energy ten tons of blazing jet fuel could deliver to the towers’ hearts. He chose the moment of his death as wisely as his target and his impact velocity, for the dead man Osama bin Laden now styles “Commander-General” made us forget what he was not: a weapons expert. His inspired effort at grand theft aero transcended the failure of al-Qaeda to acquire the weapons of mass destruction that have obsessed us ever since. The fear one morning engendered dominates our political culture.

However tall bin Laden may loom as a scourge of civilizations, it is increasingly clear that his arsenal is as phony as his army is small—its shelves are bare of expertise and materiel alike. But the War on Terror is anything but phony, and al-Qaeda is under withering attack by every means a hyperpower and its allies can devise. The cancer remains, but intrusive therapy is clearly taking its toll. As the attrition continues, the focus on what remains is intensifying. This concentration of fire to accelerate the enemy’s demise coincides with the contraction of the safe haven available to him to hide. A feedback loop has arisen from the intelligence that flexibility has gained. It is becoming a noose around Osama’s neck, and he has only himself to blame for the crumbling platform on which he stands.

Al-Qaeda means “foundation” in the sense of a base of operations rather than a Brookings Institution. 

In 2001, its host, Afghanistan’s Taliban, was on a war footing with the Northern Alliance, an American ally against the Soviet occupation. With the Twin Towers still standing, bin Laden ordered the assassination of the Alliance’s leader, Ahmad Shah Massoud. The blood feud this ignited bought al-Qaeda’s leadership breathing space, but eventually forced it to flee not just into the Pashtun no-man’s-land along the Pakistani border but beyond it, into Pakistan’s Northern Areas. It is a region whose lower passes are higher than the Rockies and whose winters make Tora Bora look like Palm Springs—a fine place to hide, but a ludicrous launch pad for a global revolution. On the lam and preoccupied with security and survival, not strategy, al-Qaeda is no longer a magnet for the best and brightest young jihadis. The average al-Qaeda grunt is no Atta, but a high-school dropout who lives at home.

However much the world changed on 9/11, the thousand days before and after it remain identical in one respect—Islamic terrorists killed no one on American soil. Whatever our future fears, in the here and now, al-Qaeda remains boxed. They can spike truck bombs with as much concentrated radwaste as they can steal or buy, but a frontier of plausibility still separates analytical pessimism from the hinterland of paranoia. Those who imprudently equate the modern ubiquity of high technology with terrorists becoming omniscient or infallible risk a rendezvous with cognitive dissonance.

Practitioners of urban terrorism, like those of strategic bombing on both sides in World War II, may find the psychological as well as the physical damage done disappointing. London’s civil society endured the Blitz, and cities of millions coexist with violent death today as well. On 9/11, 1 in 3,000 New Yorkers perished, but in the same year, over 1 in 1,000 urbanites were murdered in three major cities in the Western hemisphere alone.

Sept. 11 reigns supreme among media events, but that bespeaks the semiotic power of television, not the strategic impact of hijacked planes. What happened in New York and Washington pales in comparison to the bombing of London, Dresden, or Tokyo, all orders of magnitude more lethal but equally ineffectual in altering the outcome of the Second World War. Instead of roaring back to reinfest Germany’s body politic, the Nazi diaspora died out in the wilderness of Bolivia and Brazil. The Khmer Rouge escaped hanging and remains objectively as capable of entering the WMD sweepstakes as al-Qaeda. But their will is gone. The remnants of their genocidal cadres sit in forest clearings under the brow of the Dalgrek Escarpment, like troops of sullen baboons awaiting a peanut handout.

Information about weapons of mass destruction is ubiquitous in the postmodern world, but functional expertise remains rare. Bioterror is easy on paper, but the learning curve is lethally steep in practice. Likewise, the infrastructure of nuclear escalation remains difficult for nations—let alone cults of no fixed address—to acquire and operate. Especially when everyone expects them to try.

Past assessments of nuclear ambition that assume fixed R&D facilities lead to a more acute view of proliferation risks than the case of a perpetrator on the run. The standard objection is that even if al-Qaeda fails to get an atomic bomb, the fallout from one radwaste-spiked fertilizer bomb would be catastrophic. 

The answer is guarded: it is not easy to convert the fears of the nuclear freeze movement into reality. Building a bomb in the absence of sanctions entails a cadre of hundreds of PhDs directing a small army. Bin Laden’s skilled technocrats are manacled by sanctions and mercifully few. The ratio of ranting to rocket science among today’s jihadis does not point to any replay of the Manhattan Project. The fact is that Salafist Islam’s categorical rejection of science not only creates intellectual arthritis but also makes it impossible to integrate technology into the curriculum of a madrassa that would look askance at notions of the earth revolving around the sun.

The largest al-Qaeda explosives cache thus far found (in Jordan in 1999) equaled 16 tons of TNT. That’s some truck bomb,  but three orders of magnitude short of what struck but failed to eradicate Hiroshima, where a thriving financial district now abuts the well touristed memorial.

In the recent debates, President Bush asserted that al-Qaeda had lost 75 percent of its top people, but Vice President Cheney reminded us that the remainder “is bent on our destruction.” Now, 18,000 is a formidable force of homicidal fanatics to unleash on any nation, but we are not alone. Al-Qaeda has enemies by the score, and its local concerns are a drain on its capacity for global action. What fraction of his resources can bin Laden sustainably devote to force projection on the far side of the world?

Three decades ago, al-Qaeda was a sort of multinational PLO, an IRA with a worldview refracted through the dark glass of Salafist Islam rather than Marxism. What do we do if it reverts to type? The question may not be academic. The world is far from cured of the paroxysmal metastasis of bin Laden’s cult, but this malignant growth on the body of Islam has shrunk in response to intervention both surgical and strategic.

But what of the claim that he is a power to be reckoned with within the world of Islam? Volumes have been written about Wahhabi evangelism and Osama’s charismatic power, yet scarcely one Muslim in 100,000 has actually signed up for his jihad—good news, considering that we have over 1.3 billion Muslim contemporaries. If Osama were the culture hero he aspires to be, he would have a horde on horseback behind him that would put Saladin to shame. Instead, no more Islamists answered his call to arms than Marxists did Che Guevara’s. If the Church Militant had found so little European zeal at the turn of the 12th century, the crusades would have gone down in history as a 20-platoon fiasco.

All faiths have their crosses to bear, and one bloody-minded zealot per 100,000 is, alas, the norm. Buddhism shudders at Aum Shinrikyo’s adoption of nerve gas as a Tantric sacramental, just as Christianity does at the Ku Klux Klan and the Reverend Jim Jones. It did not take a Thirty Years War to put them out of business.

Islamic militants may drool over weapons-show catalogs and dream of acquiring what they see in them, but they are looking through a window into the rapidly receding past. The technology-fed arsenals that provided harness for the WWIII that was never fought between the superpowers have moved on. The most modern weapons Saddam’s billions could buy ended up turning Iraq’s late Republican Guard into multispectral eye candy for artillery spotters when America’s JSTARS crews materialized like time travelers with equipment from the next millennium. What justifies the breathtaking cost of America’s high-tech military procurement is that it buys a lease on the future, where we so own the battlefield that no one wants to face us in pitched battle on it.

Yet there is more to conflict than hardware. Even in the WMD era, a Clash of Civilizations requires the dispersion of compelling beliefs more than the concentration of mere zeal. For faith to manifest itself in the redirection of history often requires a vacuum into which ideas can expand into consequences. Unless, as seems unlikely, Islam implodes before our eyes into a perfervid militancy unseen since the 7th century, al-Qaeda may remain unable fill its half of the Plain of Armageddon—or the Superbowl, for that matter. The sum of all thugs falls 3,000 short of the number of airliners available, and newly minted airport guards outnumber al-Qaeda’s minions 2.5 to 1. What about weapons of mass destruction? To those who have agonized about them for decades, an epidemic seems as improbable as a few cases of devastation seem inevitable. Despite the continuity of motive and opportunity, just a handful of targets have drawn fire, and only the Lebanon Marine barracks truck bombing, the Cole, and the attack on the Pentagon have been militarily significant

Stealing hydrogen bombs, like breaking into Fort Knox, is hard work; the score is still zero despite half a century of trying. So attention turns to the relatively portable and unguarded. Al-Qaeda is always looking for a ship full of hazardous cargo to hijack, simply because one small ship out-carries a fleet of 747s. A kiloton of the least explosive cargo imaginable still dwarfs the destructive potential of airliners in collision. But merchant ship piracy is as much a fact of life now as in the days of letters of marque and reprisal, and the ongoing megaton trade in explosive ammonium nitrate makes ship detonations, as at Port Texas, inevitable disasters of peace, as bad as the Kobe earthquake, but not the end of the world. Terror is to a degree self-limiting because risks rise as weapons increase in complexity and size. As societal vigilance grows, that risk is multiplied until failure becomes the norm.

Being hunted across the world may have improved the tenor of al-Qaeda. Were its 18,000 postulated recruits all as smart, organized, lucky, and effective as Atta & Co., each might claim 146 victims. But that would leave all of them dead and 99 out of 100 Americans alive and very angry.

                                                       The 2,977  Ground Zero Fallen

WMD's in al-Qaeda’s hands pose less a threat of annihilation than one of America facing the lethal norm Europe and Japan experienced in World War II.  Such a war with terror rather than on it has not begun because the enemy lacks the means to fight it. Unlike the Axis, the amply evil bin Laden doesn’t have an army—or an aircraft carrier. Pearl Harbor was never in danger of becoming a collective noun. The indifference that led to Dec. 7, 1941 gave rise to its antithesis— constant vigilance as a policy so universally evangelized that it took a generation to relax into the torpor that made Sept. 11, 2001 possible. Osama bin Laden at large sustains our attention in ways that preclude 9/11’s repetition.

This brings us to something hard to face: some things end at their beginning, and al-Qaeda’s best shot may have been exactly that. Something perhaps a hundred times worse still hangs over us, but not the Damoclean existential threat the real zealots want. When civilizations clash for ages, their roughest edges dull first, and the risk of their mutual destruction grows less assured. Once the rhetoric of extinction threatened to cow us into abandoning all thought of confrontation with an Evil Empire. Now it serves to inflate into satanic stature a merely evil man.

Late this winter comes the day the War on Terror will have lasted longer than WWII. It will be a time to ask if, in the frozen moment, one side may still be too bruised to consider victory and the other too proud to contemplate defeat. Osama once called America a “weak horse,” but as al-Qaeda’s forces wane, the shadow this pale rider casts upon the earth is looking ever less caliphal and more quixotic.

                        THE TALIBAN'S TECTONIC NEMESIS

THE SLOW TECTONIC VIOLENCE THAT STAGGERED PAKISTAN 20 YEARS AGO RETURNS FOR THE TALIBAN

A World Turned Upside Down

 

The aftershocks of Pakistan's last earthquake are still being felt. 


BY RUSSELL SEITZ 
 

 

When Kipling was a cub reporter in Lahore, the area struck by the great earthquake of 2005 was a blank on the map separating British India from the "Khanates of Chinese Turkistan." Washington scarcely cared if the Victorian Empire needed a weapon of mass destruction called the Maxim gun to deter hotheads along the Northwest Frontier, for it was a long way from anywhere. Now America's concerns are more ecumenical and acute, for Pakistan's 1998 bomb test has conjoined the world's great monotheistic religions in a nuclear trinity.

 

There's no predicting the outcome when a natural disaster strikes an inexperienced nuclear state bordering two others. The aftershocks may loosen Pakistan's postcolonial grip on its wild and woolly Northern Areas, or shake its fragile truce with India in long-partitioned Kashmir. The quake rattled Pakistan's armories, nuclear and conventional, shattered its military academy, and left some of its general staff sleeping in the streets alongside a million other traumatized citizens.

 

It also severed the Karakoram highway, the amazing but fragile artery linking Pakistan to its conflicted frontiers and providing western China's only direct connection to world trade. The new North-South strategic highway runs through a landscape as unstable as the region's politics, for the Indian subcontinent has been thrusting into the heart of Asia since the days of the dinosaurs, raising some of the highest mountains like the bow wave of a dreadnaught and garlanding them with metamorphic treasures like the sapphires of Kashmir and the rubies and lapis lazuli of Hunza and Badakhshan.

 

This tectonic beauty comes at a high human cost. Last December, the far edge of the Indian Plate popped open a 1,000-kilometer split in the Andaman seabed, raising the tsunami in which 300,000 perished. Now the same great plate's 60-mile-deep keel has surged forward, nudging peaks like K-2 and Nanga Parbat a little higher, and knocking the ground out from under everyone from Kabul to Kashmir.

North of Srinagar, in India's Vale of Kashmir, villagers blocked highways demanding aid for stricken mountain hamlets. Scientists and climbers are missing, too, for the stunning exposure of living rock on 25,000-foot peaks and the flanks of the Indus gorge make the region a geological and mountaineering Mecca.

 

The exaggerated verticality of northern Pakistan makes it scientifically transparent but politically opaque, with borders hard to define and harder to guard. The chaos in the quake's aftermath has put the field in motion for fugitives of all stripes. Al Qaeda cadres and Islamist Kashmiri separatists can readily lose themselves among the flux of refugees in a region famed for discreet hospitality. 

 

It cannot have escaped Osama Bin Laden's attention that in the 19th century the Aga Khan spent tranquil years in Hunza while internecine war made him a hunted man elsewhere in the Islamic world. Today, the Raj has evaporated in India, but in Pakistan's Northern Areas some local notables' business cards still read "Head of State." Political parties--some religious, some ethnic--have proliferated in the Punjab and the parts of southern Pakistan that share an Urdu culture with India; but in the North, men owe their first allegiance to where they were born, not to where politicians in Islamabad  or New Delhi want borders to be.

 

The region's isolation in the months to come could erode Pakistan's often-resented efforts to integrate the linguistically and ethnically distinct populations of areas like Baltistan, a "Little Tibet" where mountains five miles high enforce local autonomy--and where the central government's authority fades out of sight of the now-obliterated roads built to enforce it. The temblor's timing is itself disastrous, for the north helps feed Pakistan, and harvests have been isolated from the urban markets by the wholesale destruction of infrastructure. 

 

Far away, in Karachi and Quetta, the political impact is being felt, as food prices soar despite the imposition of price controls. A month ago, polo was being played at 11,000 feet in the summer pastures of the north. Now the monsoon has combined with the quake to set slow-motion boulder-falls down the Indus Valley, with a hard freeze to follow. Only come spring will Pakistan know the true toll in areas too high for helicopters.

 

The Indo-European frontier was already an ethnic and religious crossroads when Alexander the Great passed through. It has seen the rise and fall of whatever gods were worshipped in the era of the Mohenjo-Daro civilization, and then of Gandharan Greco-Buddhism; but only in the last few decades has the upper Indus begun to see much of the outside world. Even in four-mile-deep valleys isolated as Kipling's not-quite-fictional "Kaffiristan," Internet cafés are up and running; and this winter, un-wired teahouse firesides may be enlivened by well-armed Afghans driven across the borders of Kunar and Badakhshan by U.S. or U.S.-backed forces. Still, equating Islam on the Upper Indus with the Taliban is as inane and dangerous as representing the Ku Klux Klan as typical of American Christianity; for while hidebound Salafist mullahs may prevail in one mosque, a valley away female education may be compulsory and Ismaili merchants may come and go from around the world.

 

Mountains like the Karakoram and the Hindu Kush will go on rising whether borders or empires stand or fall, and the erosive force of the Indus River will sweep away whatever the angry earth throws down as the tectonic plates continue their collision. The 2005 quake was as powerful as the one that leveled San Francisco, but one of these centuries the rafting together of the Asian and Indus plates will rock the subcontinent with quakes a hundred times stronger, as it has before. 

 

It may take a harder shock than this to persuade the subcontinent's capitals to recognize that, partition notwithstanding, they are in the same tectonic boat. The region's conflicts may seem intractable, but the Earth is ever patient in its diplomacy. The civilizations of South Asia have eons of grace in which to resolve their age-old differences before the slow tectonic violence that has put fossil seashells atop Everest crumples Ceylon--unserendipitously--into the mountainous seashore of Tibet.

CANUTE DERANGEMENT SYNDROME: THE TIDE ALSO RISES

In December 2023 President Trump said sea level would rise:

" 1/8th of an inch in 300 years."

In April 2024, at Mar A Lago, he told Tucker Carlson it would rise:

" 1/8th of an inch in 400 years."

In July 2024 he downshifted to :

" 1/8th of an inch in the next 497 years."

Which in October 2024 became:

" 1/16th of an inch in the next 400 years."

After defunding the National Oceanic & Atmospheric Administration, America's Oceanographer In Chief announced on July 31, 2025 that:


The metric equivalent of the latest Presidential sea level rise estimate, "1/100th of an inch in 300 years."  equals 847 nanometers ( .847 Micron) a year , which is about one third the diameter of a water molecule an hour.

                                  THERE THEY GO AGAIN


The expression "Red Team" entered the vocabulary of the climate wars in 
2014, when the American Physical Society (APS) staged a workshop to review its position on climate change in Brooklyn, New York. It was chaired by former British Petroleum Chief Scientist, JASON head and  DOE undersecretary Steven Koonin, then vice-chairman of the APS Public Affairs Panel.
 

The workshop adopted a red team/blue team format in which three mainstream climate scientists Isaac HeldBen Santer and William Collins debated three skeptics John ChristyJudith Curry and Richard Lindzen over questions challenging the IPCC’s  2013 Fifth Assessment Report . The workshop’s transcript describes this as a red team/blue team exercise to test the robustness of climate science claims.

LLM'S SAY THE DARNDEST THINGS : I'M SORRY I ASKED

 GROK  BLOWS THE WHISTLE  ON MUSK ON MARS:

Since a millibar is , in terms of human survival, no kind of atmosphere , and providing Mars with a lifespan sustaining partial pressure of oxygen globally seems thermodynamically implausible , is it fair to say that Mars will not be terraformed in fewer than ten human generations?

GROK: Let’s break this down with the data and reasoning at hand.
Mars’ current atmospheric pressure averages 6 millibars (0.6 kPa), compared to Earth’s 1013 millibars (101.3 kPa). Human survival requires a minimum partial pressure of oxygen around 16 kPa—about 160 millibars of pure O₂, or 21% of a 760-millibar atmosphere (Earth’s sea-level equivalent). Mars’ atmosphere is 95% CO₂ with only 0.13% O₂, so its partial pressure of oxygen is effectively negligible (around 0.008 millibars). This makes the surface uninhabitable without pressure suits, as humans would suffocate instantly, and bodily fluids would boil due to the low pressure, as discussed earlier.
Terraforming Mars to achieve a life-sustaining partial pressure of oxygen globally—say, 160 millibars of O₂—requires creating a much denser atmosphere. Estimates suggest a total pressure of at least 300–500 millibars, with 20–30% oxygen, to support human breathing without suits, while also providing enough pressure to prevent bodily fluids from boiling (the Armstrong limit is around 62 millibars for pure O₂). This would require adding massive amounts of gas to Mars’ atmosphere.
Thermodynamic and Practical Challenges
Mars lacks a magnetic field, so solar wind strips away atmosphere over time (about 100 grams per second, per NASA’s MAVEN data from 2015). Any added atmosphere would need constant replenishment. The planet’s CO₂ is mostly locked in polar ice caps and regolith—estimates suggest melting the caps might yield 10–20 millibars of CO₂, far short of what’s needed. Producing oxygen on a planetary scale, likely via electrolysis of water (if subsurface ice is accessible) or CO₂ (via the Sabatier reaction or solid oxide electrolysis), is energy-intensive. Mars’ solar flux is 43% of Earth’s, so solar power is less efficient, and nuclear power would require infrastructure not yet in place.
To add 300 millibars of atmosphere, you’d need to generate around 2.5 × 10¹⁶ kg of gas (assuming Mars’ surface area and gravity). Earth’s atmosphere, for comparison, is 5 × 10¹⁸ kg. Redirecting comets or asteroids to deliver volatiles (water, CO₂, N₂) has been proposed, but the energy to redirect even a 1-km comet (10¹² kg) is immense—about 10²⁰ joules per comet, requiring thousands to make a dent. Current proposals, like those from a 2018 NASA study by Jakosky and Edwards, estimate that even with optimistic assumptions (e.g., releasing all CO₂ from regolith), Mars might reach 20–40 millibars, still far below habitability.
Timeline for Terraforming
A human generation is typically 25–30 years, so ten generations span 250–300 years. Terraforming Mars to a breathable atmosphere involves:
  1. Increasing pressure: Adding 300+ millibars of gas. Even with futuristic tech (e.g., self-replicating factories producing greenhouse gases or oxygen), the energy and material requirements are staggering. A 1991 study by McKay, Toon, and Kasting estimated 100–1,000 years to raise pressure to 100 millibars using perfluorocarbons for greenhouse warming, but oxygen production would take longer.
  2. Oxygen production: Photosynthesis (via imported plants) or industrial processes to convert CO₂ to O₂ would take centuries. Earth’s oxygen-rich atmosphere took billions of years to form via cyanobacteria. On Mars, even with engineered microbes, estimates range from 10,000 to 100,000 years for a breathable O₂ level (Fogg, 1995, Terraforming: Engineering Planetary Environments).
  3. Sustainability: Without a magnetic field, atmospheric loss continues. Artificial magnetic shields (proposed by NASA in 2017) are speculative and untested.
Is 10 Generations (250–300 Years) Feasible?
No. The energy, material, and time scales involved make terraforming Mars to a breathable state within 300 years implausible. Jakosky and Edwards (2018) concluded that with current technology, Mars’ resources are insufficient to create a habitable atmosphere even over millennia. Industrial processes might raise pressure to 50–100 millibars in a few centuries with extreme effort (e.g., Zubrin’s The Case for Mars, 1996, suggests 100–200 years for minimal pressure increases), but breathable oxygen levels would take far longer—likely 10,000+ years—due to the slow rate of O₂ production and atmospheric retention issues. Ten generations is a drop in the bucket compared to the geological timescales required.
Counterpoints and Speculation
Some optimists, like Musk, have suggested faster timelines, but these often rely on unproven tech (e.g., nuclear explosions to melt polar caps, which would yield minimal gas). Advanced nanotechnology or fusion power could accelerate processes, but these are speculative and not imminent as of 2025. Even then, oxygen production and atmospheric retention remain bottlenecks. Paraterraforming—creating enclosed, habitable domes—is far more feasible within 300 years, but that’s not global terraforming.
Conclusion
It’s fair to say Mars won’t be terraformed to a life-sustaining state in fewer than ten human generations. The thermodynamic and logistical barriers suggest a timeline of thousands, if not tens of thousands, of years for a breathable atmosphere, if it’s achievable at all.
