And how do you declare "victory"
You can't. We can, and should, declare war (haven't bothered yet) against nation states who actively seek to harm us (and YES, I believe in pre-emptive strikes). I have no problem at all in hunting down and killing any known terrorists or terrorist enablers, either.
This, however, is fated to be no different than the "war on poverty" or the "war on drugs." No clear goals, no way to get accountability, and sn eternal metastasizing of the "war effort."
As long as there is one poor child, as long as there is one kid smoking a joint somewhere, as long as there is a Mustafa in a a cave slobbering over the Koran with an RPG, the war must go on. Using that type of terminology is silly, and actually cheapens our efforts to resist terrorism.
"WAR" is a term for total destruction of an enemy, not for fighting an ideology.
Israel has been resisting islamofascism FAR longer than we have, and they don't resort to silly emotionally manipulative phraseology. They just kick ass when Egypt, Syria, or whoever comes after them....., and they hunt down and kill terrorists. We could learn a thing or two from them.
Blah, blah, blah.
