The Bush Doctrine assumed that America must spread democracy all over the world (however, if democracy exists in the US is not clear!). The Bush Doctrine potentially predicts that, once democratic institutions exist in some country (for example in Iraq), democracy as a political system is going to be spread over to all neighboring states in the region, and subsequently all these countries would adopt democratic peaceful policies in international relations (nevertheless, why the US as “democratic” state is not adopting a peaceful policy in international relations is still not clear!).
