My argument is that a strike against Mecca isn't an appropriate response to a terrorist attack commited by a handful of people, even if the attack was carried out with  dirty bombs in the name of Islam. If all American laws acted in such an extreme way, we'd live in a brutally intolerant country, governed by cruelty. For example, if you are a Christian, should I hold you responsible for David Koresh's actions? Are you guilty by religious association?
