I don't think a trial is the be-all and end-all of due process where military conflict is concerned, but I see where you're coming from. We're unlikely to agree about this as I have a considerably more hawkish view on foreign policy matters than you do, I think.
True. What I keep coming back to is the staggering amount of blood and treasure we could have saved by treating 9/11 as a criminal act by a few deranged cultists, which is what it was, instead of a traditional casus belli. Our moral authority as a peace-loving nation would also be intact.
