Shocking how willing people are to assume that we'd have known exactly how to support the Syrian rebels without also benefiting the groups that would go on to form ISIS. Or, for that matter, that Hillary Clinton can credibly claim to offer a departure from Obama's foreign policy without recalling her place in the pre-2008 public imagination as a cynical opportunist.
Forgive me for my lack of enthusiasm, but I'm not excited by the prospect of another US President who draws facile comparisons between Islamic extremism and communism, or who shrugs off civilian casualties in the passive voice ("mistakes are made").
More arms for the rebels probably would mean more arms for ISIS. The whole we should have armed the rebels so that the most successful rebel group didn't get too powerful argument is ridiculous.
