Abstract
The Iraq crisis and the intra-divisions concerning the conflict have clearly indicated that it was difficult to establish a common point of view. Each country was ready to assert its opinion, regarding its position in the EU and its personal relations with the US. Even countries that were not in the Union tried to establish a "European position? on the war in Iraq (e.g., Poland). With the enlargement of the EU, the conception and the elaboration of the European defense policy will have to be reconsidered and along with the question of the relation with the US. We may wonder what will be the impacts of the enlargement on the transatlantic relations concerning the defense policy. In the first part, I will briefly describe the history and the background of the European defense policy. Then the main consequences (focused and linked with transatlantic relations) of the enlargement of the EU on the defense policy will be explained. Finally I will discuss the new transatlantic relations that may appear with the enlargement.
