Could the leadership changes resulting from Egypt's January 2011 Revolution uproot thirty years of security cooperation between the United States and Egypt? This monograph examines how the security cooperation, rooted in the Camp David Accords, supports both the Egypt-Israel Peace Treaty and other key strategic interests of the United States and Egypt. The United States gains strategic access to the Middle East region through the security cooperation, and Egypt's military protects its economic power. The monograph investigates whether new political parties and leaders, including the Muslim Brotherhood, plan to maintain or cancel the Peace Treaty. In the short-term, U.S.-Egypt security cooperation will continue as Egypt's new leaders plan to adhere to the Peace Treaty, despite the cold peace with Israel.
