The Iraq War has provoked a conflict or crisis within the Atlantic Union led by U.S.A., which is characterized by multilevel and complexity. It finds main expressions in differences between America and the European Union led by France and Germany, and differences between major member countries and between new and old members within EU as well. The cause of the crisis is rather complicated, involving many factors such as changes of the world structure and European security situation, international political ideas, global strategic arrangements, member countries' actual interests and challenges of their policy changes to existing EU relations. The influence of the Atlantic Union crisis is far-reaching.
