Could you make allowances for non-Americans and explain your point?
9/11 is a monstrous war crime without precedent in the american experience. As terrible as the loss of life is, it represented something much bigger: a direct challenge to the whole of america with the targets being selected as representing its economic system, its defense establishment, and it's democratic form of government. If they had ten or 20 planes, I'm sure they would have added other targets, such as churches representing its religion. The challenge is even bigger than that - although euros appear to find little in common between their own societies and america, 9/11 actually represented a challenge to all of western civilization, america being almost the last country, for many years, being willing to defend the values of that civilization, such as democracy, with force when necessary.
There is absolutely no alternative but to fight back - not take it to the corrupt bureaucrats at the UN, not expect much in the way of help from our "allies" (except the Brits). In his fatwah, Osama specifically declared war against ALL americans and specified them ALL as "targets" - men, women, children, old people, sick people. In doing so, he stooped to a level that even the nazis didn't reach in WWII.
I'm angry that there are still people who don't get it. For eight tears, there was the insane wholesale reality disconnect of the Clinton Administration - generally treating WW4 as if it were an issue of arresting a few people.
Although president Bush understands it's a war, he seems beset by a "Maginot Line" mentality - he wants to spend zillions of dollars to "protect" everything. I just heard a report that they want to handle the SAM threat against passenger jets by installing ECMs - at a cost - just for THAT "defense"! - of $20 billion. There is no "defense" - that's replaceing the Clinton delusions with new delusions. There's only offense, the U.S. has to go on a real war footing, implement completely new strategies, methods, technologies, weapons, and rules, and go after them. They'll stop when they're dead - we need to make them dead.
