A new survey finds more than 80 percent of Americans oppose the war in Afghanistan, making the occupation potentially the most unpopular in U.S. history. The poll by CNN and ORC International found just 17 percent of Americans support the war, a steep drop from 52 percent five years ago. CNN reports the disapproval numbers are higher than comparable data for both wars in Iraq and Vietnam. Only a quarter of Americans want U.S. troops to remain on the ground beyond 2014. But the Obama administration is currently pressuring Afghanistan to accept a deal to keep U.S. troops beyond that deadline. A new U.S. intelligence report predicted U.S. gains from the 12-year conflict will be eroded within three years without a large military presence.
