In interviews with major papers and appearances on TV, General David Petraeus has launched a public campaign on behalf of the so-called "counterinsurgency" strategy in Afghanistan. He says he'll give President Obama his "best military advice" when it comes to the timetable for American withdrawal. Obama wants US troops to begin withdrawing from Afghanistan next July, a deadline many think unrealistic. Rajiv Chandrasekaran, senior correspondent and associate editor at the Washington Post, recently interviewed Petraeus in Afghanistan.
