Israel vs. the realists.
Israel's Ambassador to the U.S. Michael Oren takes after realists in a piece in Foreign Policy. His basic position is that realists don't appreciate that Israel is in fact the ultimate American ally and a net-plus for America's security and economy.
The one odd element to the piece is that it's devoted to debunking arguments that are essentially irrelevant. Sure, there are realist analysts and academics who do not believe Israel is as strategically valuable to the U.S. today as it was during the Cold War - but so what? One could understand the impetus to Oren's piece if the realist argument were actually gaining traction and threatening ties between the two countries in some material way - but as far as I can tell, it is not.
Indeed, the actual debate over Israel in the United States has nothing to do with first order questions (whether we should be allies) or second order questions (whether Israel is a net-plus for the U.S. strategic ledger) but third order questions about whether we should pressure Israel to make concessions to the Palestinians to further peace negotiations - and that debate was settled a year ago.
