Let us review our history in warfare over the last hundred years:

WWI - Helped to defeat the Wehrmacht, then stood by as they grew into an even greater military power in twenty years.

WWII - Helped defeat the Axis and Japan, then assisted the formation of the Soviet Union followed by forty years of cold war.

Korea - Helped contain the North Koreans who continue to be an unstable and worrisome dictator state.

Vietnam - Lost to Communist North Vietnam at a tremendous cost in lives and money.

Iraq - Beat them in Desert Storm quickly then back to business as usual.

Iraq II - Got rid of the dictator, then stayed way too long at a huge cost in lives and money, leaving the country destabilized.

Afghanistan - Eventually got Bin-Laden but accomplished little else. The Taliban is still strong and we fostered additional hatred among Islamic fundamentalists.

Now you say we need to go to war to fight an enemy that is indistinguishable from the general population, who are more than willing to die to take American lives, and who believe they are ordained by their God to kill infidels. NO THANKS!
