Nations don't make "friends," they make alliances, although these mutually useful agreements are couched in the language of "friendship" for public edification. These "friendships" are delicate constructions that are susceptible to changing dynamics in the rest of the world. The U.S. was once the "friend" of both Iran under the Shah and Iraq under Saddam. It is still at odds with Iran, but there is now an apparent need for rapprochement. But regime change is not the only criterion that differentiates a "friend" from a foe. The U.S. and Libya were enemies under Qaddafi, and now the relationship is warming, still with Qaddafi at the helm. The "friendly" relationship between the U.S. and Israel can also change, despite the strong pro-Israel lobby in the U.S. There is nothing magical that guarantees the enduring nature of this present relationship. And, if it were to change for the worse, the big losers would be both Israel and American Jewry.
