Joe Klein on the situation in Afghanistan:

Taken together, the emerging Pakistan and Afghanistan policies sound ... impossible, but unavoidable. They will also be politically treacherous. Already, John McCain has made it clear that his position on Afghanistan will be the same as it was on Iraq in favor of more troops. Obama could easily find himself in the same sort of hawk-vs.-dove debate that has boggled American Presidents from Vietnam to Iraq. Traditionally, Presidents favor more troops and precipitously lose public support. In this case, Obama's margin for error is minuscule, given the enormity of the economic crisis. He simply can't get bogged down in Afghanistan. And he simply can't allow al-Qaeda and the Taliban free rein. And every option in between seems either a gamble or a fantasy.
