I disagree. They'll say yes but what they will say yes to will be to do essentially nothing and get paid extremely well for it. Kerry is a dolt who has given away the US bargaining position. For him, getting a yes (of ANY kind) will be more important than anything else and he will pay dearly for it.
Actually, you don't disagree but have suggested a possible outcome. we will pay thru the nose for empty promises.
Another thought that I had was that perhaps this a brilliant stategy by Kerry. He blamed America for Vietnam and weekened our position by testifying before Congress and repeating scurrilous charges of our soldiers, meeting with the enemy while he was still commissioned (how do you spell treason), voting against for most of our weapons systems, after the 1st world trade center bombing voted to cut intelligence, his ridiculing Allawi while he was visiting the US, etc. His consistency was to make America weaker and acquiesce to the global powers. In this context, his plan for the summit makes sense.
