"Israeli Prime Minister Benjamin Netanyahu canceled plans to attend, aides said, because he feared Egypt and Turkey were going to embarrass Israel with complaints about the unacknowledged nuclear program the Jewish state is widely assumed to have. A senior Arab official involved in summit planning insisted Friday that the Arab countries had no such plans. "There was no intention to politicize the outcome of the summit," said the official, who declined to be identified. Nevertheless, the issue is expected to come up. On the agenda for Obama's meeting with King Abdullah II of Jordan on Monday, for example, is a discussion of Middle East peace. Also high on the list at the president's series of meetings is how to impose sanctions on Iran to curb its nuclear program."
