Studying the U.S foreign policy is one of the most important issues in international relations. On the other hand, Middle East region has also been the central issue for the U.S politicians because of its geopolitical role in the world. In better words, the U.S is pursuing an increasing role in this region and of course there are a lot of elements which influence U.S policy-making in this regard.

Applying James Roseau’s model, this dissertation is going to prove the importance of lobbies in shaping the U.S foreign policy, specially the U.S policy in the Middle East. The Zionist lobby among these lobbying groups has a great role to preserve Israeli interests in the region and shaping U.S policies in the region. AIPAC is the main Zionist lobbying group which is trying to do so through its solid structure and financial supports of bills and plans in the U.S government. This dissertation studies the way and means through which the AIPAC is going to achieve its goals.

The AIPAC main goal is to lead U.S Middle East foreign policy in accordance with Israeli interests in a way in which there could be no opposition to those policies. We are witnessing many examples of these lobbying actions in U.S policies toward Iran, Iraq and Syria.

The AIPAC’s activities in U.S government have resulted in U.S hostile policies against Iran. It is clearly observable in increasing political and economic sanctions and even military threats against Iran from 2001 to 2006. At the end of the dissertation I have been mentioned several policies through them Iran can influence the U.S foreign policy and lobby inside the American political community.
