Obama mentions Henry the K is a McCain adviser who happens to contradicts McCain's own reluctance to speak to Iraq and explains the "no pre-conditions" doesn't mean a "tea party"...uses history (N. Korea) to make case for diplomacy with enemies...mocks McCain's recent gaffe regarding be ing unwilling to meet Pres, Zapetara of Spain...

McCain claims diplomacy gives undue credibility to the enemy.

Not if done properly! I yell at TV.
