Speculation about a possible attack on Iranian nuclear sites has reached a fever pitch over the summer. The talk is so wild that even level-headed commentators on the right like Michael Barone opine aloud that perhaps Israel won’t be the instigator; rather the Obama administration might order a U.S. strike.
This still seems beyond unlikely but there is no question that the climate has changed. True, the president’s National Security Advisor the other day reiterated the administration’s willingness for Obama to meet with his Iranian counterpart assuming certain conditions were met—conditions that no one expects will be met. But inside the White House and national security bureaucracy, opinions about Iranian behavior and intentions appear to be hardening. Robert Kagan recently recounted a briefing by the president and top officials in which they made as clear as they could that their patience with Iran has all but run out.
