I don't see how. Obama is pursuing the same foreign policy on North Korea that America has pursued for almost the last two decades. America isn't being 'played', we know exactly what is going on and we're doing it on purpose because it's the best policy we have available.
If people think that Obama believes he's going to be able to negotiate North Korea into becoming a responsible member of the world, dismantle its weapons programs, etc, they are terribly naive. He's playing the same game we always play. All we care about is North Korea staying in its hole.
