Dwight Eisenhower, when he was running for re-election in 1956 and simultaneously trying to contain growing instability in the Middle East as a result of tensions between Israel and its neighbors, wrote a letter to an adviser as follows:
Of course, nothing in the region would be so difficult to solve except for the underlying cause of the unrest and dissension that exists there -- that is, the Arab-Israel quarrel. This quarrel seems to have no limit in either intensity or in scope. Everybody in the Moslem and Jewish worlds is affected by it. It is so intense that the second any action is taken against one Arab state, by an outsider, all the other Arab and Moslem states seem to regard it as a Jewish plot and react violently. All this complicates the situation enormously.
“As we began to uncover evidence that something was building up in Israel, we demanded pledges from Ben-Gurion that he would keep the peace. We realized that he might think he could take advantage of this country because of the approaching election and because of the importance that so many politicians in the past have attached to our Jewish vote. I gave strict orders to the State Department that they should inform Israel that we would handle our affairs exactly as though we didn't have a Jew in America. The welfare and best interests of our own country were to be the sole criteria on which we operated.”
