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.
The Hagel nomination comes at a critical moment. Some experts believe that Iran may soon amass enough enriched uranium to give it “breakout capacity” — allowing it to quickly produce a nuclear weapon at a time of its choosing. Meanwhile, there are signs that the Obama administration’s strategy of tough international sanctions, backed by the threat of force, may compel Tehran to negotiate a deal that would forestall a confrontation.
Achieving success in nuclear negotiations requires the administration’s full commitment to increasingly painful sanctions, a credible threat of military force and a reasonable diplomatic alternative. This approach may not be sufficient; Iran may be bent on achieving a nuclear weapon. But any deal will be built on a stool with those three legs. If the administration goes wobbly on any of them, the stool collapses, at which point either Washington employs military force to destroy or delay Iran’s nuclear program or Israel becomes likely to act on its own.
Even supporters of Hagel’s nomination must admit that it is nearly impossible to find any support in his record for the idea of “prevention” that undergirds the strategy toward Iran. This concept, which has been publicly embraced by Obama, means that the United States should deter Iran not from using a bomb but, rather, from acquiring one — preventing Tehran peacefully, if possible; through military means, if necessary.
Whole thing here.
