I hope he does. The RNC can draw parallels with Kerry's pronouncements and judgement on Vietnam in 1971 and show how wrong he really was. Once Kerry starts talking about an exit strategy, the message to the enemy is that the US has lost its will and will get out if they intensify their attacks on our personnel. Not a good message.
Kerry's "I'll get us out" message requires him to tell us how.
It'll go nowhere.
