The "end of the Cold War" was probably also a factor. Russia had armed the Arab countries of the Middle East for decades. With the "end of the Cold War" This problem had supposedly ended. But Russia has changed much less than everyone (except Golitzen) thought they had.
Well, part of the solution was Richard Nixon(who should've won the Nobel Prize and not Carter) granting more funds than the Soviet Union to Egypt, which was becoming a Soviet State. I think that that was a big, big reason why Egypt became friends with Israel and so I give Nixon credit for that. I do find it funny, however, the call to cut funds from Israel and not Egypt.
