The morning after, I'm reminded that the intriguing difference of opinions in the debate was Barack Obama saying he'd be happy to meet personally with the heads of Syria, Iran, whatever whereas Hillary Clinton emphasized that the Bush administration had sidelined diplomacy too much, but said she'd only go so far as to actually meet with these people as the end of a diplomatic process, lest the meeting become a propaganda coup. Dana Goldstein says "Edwards agreed with her," though what I saw was him mostly equivocating.

At any rate, it's not a very important issue as such, but perhaps a window into wider disagreements about national security. Clinton articulated a position of continuity with her husband's administration, while Obama was hinting at a more drastic departure.
