Special op troops certainly ain't going to do it. Neither will immigration controls. The only solution is to remake the world by removing the sponsoring regimes like Iraq and key players like OBL and Arafat. We have plenty of technological capability to do that -- technology or force-projection isn't rate-limiting, side effects are. The immediate and overriding problem is that we are already in a MAD situation w.r.t. Saddam Hussein: even if we nuke him, his sleepers could destroy our cities overnight. I don't know that there is a solution but, watching Bush, Cheney et al, it is clear to me that they understand the situation. You don't, evidently, but that doesn't stop you from pontificating, of course.
