However, if Iran and N. Korea coordinate their move, this would not work. He has to let one of them scot-free, while taking down the other.
One complicating factor is the case of Chia Head getting greedy and selfish. If he tries to play U.S. against China and settle for grand deal with U.S., he will get the ire of China and upset Iran.
On the other hand, if he simply creates (military) provocation from time to time and try to wring concessions from U.S. as much as possible while not crossing Iran and China, things will go smooth for him, if the current situation continues. This is the safest course for Chia Head.
Which way Chia Head chooses, one thing is for sure. There is no way he can declare all nuke material and facilities, and agree to complete inspection. He knows Bush just needs enough cover to spin it as a great success. Bush does not have leverage to comple Chia Head to stick to complete disband of nuclear program.
