As has been well documented, not everyone is so pleased that President Obama nominated former Senate colleague Chuck Hagel, a Republican, as the next secretary of defense.
Some of that has to do with Iran sanctions. Groups like the Republican Jewish Coalition and the Emergency Committee for Israel have noted that Hagel opposed them repeatedly when he was a senator - a big no-no among Israel hawks. ECI, meanwhile, has blasted Hagel for opposing military action against Iran as irresponsible.
Iran sanctions came up during the presidential race last year, as Mitt Romney and Republicans blasted Obama for going the multilateral route, eschewing U.S.-originated unilateral sanctions and instead gathering international support.
While one might assume that Hagel falls neatly in line with this Obama sanctions paradigm - multilateral good, unilateral less effective - it's worth noting that Hagel found himself on the opposite side of Iran-sanctions bills from Obama, Vice President Joe Biden, and new secretary of state nominee John Kerry.
