It is correct to say that the Israelis alone are the ones who must decide whether to attack Iran. It does not follow, however, that discussion of whether Israel should do so has no place in this country’s presidential election. Among issues of great import, few have more claim to be front and center in this presidential campaign, since the U.S. president is destined to play a crucial role in the outcome. Once before, in 1948, Israel owed its existence in part to an American president, Harry S Truman. Today, another American president may hold the key to Israel’s fate. Voters need to know, for America’s sake as well as Israel’s, whether the man they elect in November has the right stuff.
