Sixty percent of Americans say the war in Afghanistan has not been not worth fighting and just 30 percent believe the Afghan public supports the U.S. mission there — marking the sour state of attitudes on the war even before the shooting rampage allegedly by a U.S. soldier this weekend.

Indeed a majority in a new ABC News/Washington Post poll, 54 percent, say the United States should withdraw its forces from Afghanistan without completing its current effort to train Afghan forces to become self-sufficient…

Against that backdrop, the number of Americans who say the war has not been worth fighting, at 60 percent, is up by 6 points from its level last June to just 4 points from its peak, 64 percent, a year ago. Intensity of sentiment is deeply negative: Forty-four percent feel “strongly” that the war has not been worth fighting. Just 17 percent, by contrast, support it strongly.
