You make a LOT of reasoning assumptions
And I don't think I can find one that is correct.
ObL does not speak for most of Islam.
No one does.
When we kill off ObL and the Taliban he runs, he/they will fade into the dustbin of history, like all other evil despotic tyrants when they are killed off.
So what if there a lot of Moslems?
There a lot more people who are not.
We tried negotiating with ObL the last ten years or so.
We got 911 as answer.
The only acceptable negotiating option available is triumph for us.
