"As a member of the team that negotiated the Camp David peace treaty with Israel in 1978, he can be expected to abide by all of Egypt's existing commitments to Israel, analysts and former colleagues said. But he is renowned for having voiced reservations about some of the treaty's clauses to then-President Anwar Sadat, and "will not be willing to accept Israeli excesses in the occupied territories," said Mustapha Kamel al-Sayyid, a professor of political science at Cairo University. "Public opinion in Egypt is in favor of a less soft approach to Israel, and I think he shares this feeling," he added. "It will be very difficult for him to make the kind of concessions Hosni Mubarak made to Israel," such as during the 2009 Gaza war, when Egypt closed its border with Gaza. Elaraby is also likely to be more open to establishing diplomatic relations with Iran, improving Egypt's frosty relationship with Syria and opening dialogue with Lebanon's Hezbollah movement, Sayyid said, suggesting that the new Egypt may not be as reliable an ally of the United States as Mubarak's Egypt was."
