Let’s stipulate that Chuck Hagel may make an exemplary defense secretary. That possibility doesn’t alter the fact that his nomination by President Obama almost certainly raises doubts among allies and adversaries alike that Obama may not be nearly so committed to using all means necessary to prevent Iran from achieving a nuclear weapon as he pledged during his reelection campaign. If the White House does not take steps soon to correct that impression, the chances for a negotiated resolution of the Iran nuclear crisis will fall nearly to zero and the likelihood of Israeli military action will rise dramatically.
