Fighting yourself?

Democracy in America: our blog on US politics The Economist: "“We’re going to know in the next three to six months whether he’s doing anything differently—whether he can seriously address the corruption, whether he can raise an army that ultimately can take over from us and that doesn’t lose troops as fast as we train them,” one of Mr. Obama’s senior aides said"

"He" is Hamid Karzai. Do I get this right? The US is training Afghan soldiers that defect and join the Taliban.
