You will never win our version of the "war on terror" overseas, because as much as we like to posture and chest thump we are dealing with other sovereign countries.
We will not be allowed to stomp around wherever we want using any tactic we deem necessary to identify and apprehend all of our enemies, the citizens of those other nations will not allow what we now accept in the U.S.
As for dropping a nuke here, dropping one there to force our will is kind of like killing a guy by holding his head next your right ear while firing a gun thru your left, we as a country would be devastated economically by the rest of the world first and then probably militarily shortly after.
Now our internal fight is another matter, I still think we can defeat the terrorists here, I see more and more resistance to the "Patriot Act fanboys", all is not lost.
