"If instability comes to Egypt, it will send shockwaves throughout the rest of the Arab world," Haas told Smith. "It's the first country to establish peace with Israel. It's, indeed, the cornerstone of what peace there is in the Middle East. So if the United States is seen to pull the rug out from under this friend which, as you noted in the report, a friend for some three decades, it will raise major questions about American reliability. On the other hand, if we're seen to give him an uncritical embrace, it could risk alienating the Egyptian people and some future government we may have to work with."
