It is axiomatic that Israel needs to maintain bipartisan support in the United States. However, if the Democratic Party gives President Barack Obama overwhelming backing on the Iran nuclear deal (as opposed to a split decision), the traditional policy may prove unsustainable. Bipartisan support also rests on a fundamental bipartisanship in other areas. It is possible to ride two horses when they are close together; impossible when they are racing off in opposite directions.
For my generation, a possible estrangement between Israel and the Democrats is an emotional issue. The Democratic Party was what French Socialists called the “vieux maison,” the old home. I still remember our inconsolable classroom after the 1968 elections and the sympathetic instructor explaining that Republican Richard Nixon’s defeat of Hubert Humphrey the Democrat was not the end of the world.
