There's a global trend towards countries getting nuclear capability - it's not a difficult thing to do if you can get the materials.
The US intends to prevent any other power becoming a rival - Condaleesa Rice said exactly that two weeks ago. That presumably means militarily and economically, in fact the two go together. Part of their strategy is to weaken or control the UN.
Plenty of countries - not just muslim controlled countries, are not surprisingly worried about coming under US imperial control, so there will be lots more small countries trying to get the bomb. It's not just the US they fear - resurgence of the UK as a colonial power, India, Pakistan and China growing in power and influence.
Iraq is just a sideshow and shows Bush's small-mindedness and opportunism in rewarding his oil industry backers.
