We don't give enough credit to the brilliant strategy of the Moslems. One of their tactics is to function as independent entities. They have common goals, but the tactics and strategies are dispersed among many different groups. There is no "head" to kill. In Germany, when we got Hitler, we killed the head, and the rest of the snake died. It died slowly, and there were terrorist German attacks in the post-war settlement. However, it did die. If we get Osama bin Laden, for example, there are others to take his place. The Bali bombings, embassy bombings, etc., all meet the same goals, but are the function of independent entities. I think it's very likely that Iran, Iraq, Saudi Arabia, Syria, etc, all of which provide support to the war against everyone by the Moslems, really don't have any idea about the individual terrorist activities, as it gives them plausible deniability.
On an up-note, I think we do have to recognize that the terrorists are currently so holed up that their only recent tactic has been to kidnap individuals in predominantly Moslem countries, execute them and then post it on the internet. This tactic means they have been seriously damaged. They would certainly be bombing embassies and ships if they could.
For those who think this is a new war, BTW, remember that the man who killed Robert Kennedy, Sirhan Sirhan was a Palestinian national. They've been at war with us since we backed Israel in 67. We've just ignored it, at least until 9/11.
This tactic means they have been seriously damaged. They would certainly be bombing embassies and ships if they could. Yes but we must not become complacent, or (heaven forbid) change leadership at this time. We need to stamp out the places where they find sanctuary, and continue to address where they are getting funding and teaching hatred. After all, a couple generations of no madrasas may mean the few remaining terrorists could be treated as criminals, instead of wariors in a great war against the west.
