1. This is a tough poll given that there are two separate factors here, Al Qaeda and the Taliban. The book by Greg Mortenson “Three Cups Of Tea” provides a lot of insight into the situation over there, and it’s credibility is supported by the fact that he is now an advisor to the military and his book required reading for all the commanders in Afghanistan. His interpretation is that the Taliban are primarily interested in their historic inter-tribal rivalries and are local problems not particularly involved with the rest of the world (an excellent article by Mortenson was on the MSNBC home page two or three days ago - 'Three Cups of Tea' advice for Obama - Giving- msnbc.com).
Al Qaeda, on the other hand, are the fanatics out to rid the world of the rest of us. While we might debate whether the Taliban and their poppy funding activities should be engaged, either by the U.S and/or NATO, I don’t think we/the world/NATO can ignore Al Qaeda. That means we all have some responsibility for stopping them, which includes manpower, resources and funding. The US no longer has the luxury or means of doing it all by ourselves. We all have skin in his game.
2. Nuclear devices: The argument that Al Qaeda won’t use a nuke is not realistic.
MAD doesn’t apply because a) destruction is not a deterrent to fanatics, b) Since
there is no ‘mutual – we don’t have a single opponent like the USSR – who would we ‘respond’ to? Afghanistan? Where in Afghan.? Pakistan? Waziristan? Iran? N. Korea? c) The lawyers of the world would dither forever trying to prove who was responsible, then the tree huggers wouldn’t allow a nuke response anyway.
3. Nuke Weapons Effects: A nuke has three kill mechanisms, Thermal, blast and radiation (initial and residual). Weapons can be optimized to enhance or minimize any of these – remember the neutron bomb that got politically buried years ago? A suitcase bomb would be ‘dirty – high residual’ almost by definition, given it’s crude firing mechanism. Going back to SHAPE’s ‘The NATO School” at Oberammergau among others, the blast effect of a 1KT nuke going off at ground level in London, New York or DC would be terrible (100 psi overpressure out to 340 ft, 25 psi overpressure enough to collapse a reinforced concrete house out to some 700 ft.- muffling effect of surrounding buildings balanced somewhat by fragments and debris flying from the collapsing ones – the cube rule says that if you want to double the distance for the same effect, you need 8 times the yield - going to the top of a tall building would be more like an airburst). More terrible, however, would be the fear and effect this would have on the world and it’s economy. Al Qaeda would achieve one of it’s highest goals. That looming sword deserves all the defensive measures the world, not just the US, can muster.
