Ok, but all you're gonna get from him on foreign relations ESPECIALLY is the exact boilerplate that comes out of the state department. There are actually policy reasons to stay boilerplate on that stuff, above and beyond political considerations.
That said, he did come about as close as he could to acknowledging the surge in Afghanistan didn't accomplish much. And he called for a constitutional amendment on Citizen's United, which he apparently hadn't done in public before (according to news outlets trumpeting it).
Questions about the state of Iraq, Syria, Libya, Iran, Egypt, et al would have been more interesting. Characterizing sending more troops as a hard decision is not too surprising.
