Although the President is seen as a strong leader, if he really wanted to get his point across he would simply stop paying dues to the UN. But unlike Reagan, who did cut off US funds for many years, I honestly don't think Bush has the nerve. Even if he wanted to do it, the neocons with whom he has surrounded himself, would talk him out of it.
On top of pro-abort Alberto Gonzales becoming AG, this is a sad development.
