Poll: U.S. opposition to Afghan war at all-time high

Unpopularity with the war in Afghanistan reached an all-time high in CNN polling with 62 percent saying they oppose it, according to a new CNN/Opinion Research Corp. survey. Moreover, confidence in the Afghan government is low. Seven in 10 Americans are not confident that Hamid Karzai's government can handle the situation there.

In an interview with NBC on Sunday, Gen. David Petraeus, the top general in Afghanistan, made clear that it will take a lot of time and commitment to achieve the overall goal of preventing Afghanistan from again becoming a haven for international terrorism.

"I didn't come out here to carry out a graceful exit or something like that," Petraeus said of taking command in Afghanistan this summer to replace ousted Gen. Stanley McChrystal.

Petraeus also repeated the administration line on plans to begin withdrawing some troops from Afghanistan in August 2011, saying the "transition" will be based on conditions on the ground.

The CNN/Opinion Research Corp. poll surveyed 1,009 Americans between August 6 and 10 and carries a sampling error of plus or minus 3 percentage points.
