Obama comes from the antiwar wing of the Democratic party that opposes the use of force in almost all instances. If he were still a senator and a Republican president were proposing a troop buildup in Afghanistan, Obama would probably be against it.
I recognize arguing with Barnes is like trying to beat a chimpanzee in a shit-throwing contest, but really. Obama ran for president for two years vowing an increase in U.S. troops for Afghanistan. When he was elected president, one of the first things he did was increase troop levels in Afghanistan to an all-time high. Tomorrow night he’s going to increase troop levels again by something like 30,000. That means by the end of Obama’s first year in office, he’ll have ordered more troops into the Afghan war than were there when he was elected president. Believing that Obama would oppose a U.S. troop increase under a counterfactional conditional requires actively ignoring shitloads of evidence. In fairness, if you read Barnes’s book about Bush, you’ll learn that under the ex-president’s stewardship, “al Qaeda and the Taliban had been subdued in Afghanistan,” making this whole war thing rather hard to understand.
