From my perspective, which views neoconservatism as essentially modern imperialism, Obama doesn't cut it. Nor is he an out-and-out internationalist, which I'd consider the antithesis of neoconservativsm. Honestly, he seems to be taking a fairly pragmatic approach to foreign relations, with little bits of both theories working their way in. It's one of the few areas where I think he's actually been passable.
