The “capability” debate was initially framed as one over “containment” in February, and hawks like [Lindsey] Graham found little bipartisan support until their position became a centerpiece of the AIPAC policy conference in March. But the initial resolution from Graham in May stalled. Then things rose into the national consciousness.

This month, an unprecedented campaign by Benjamin Netanyahu to get Obama to shift his Iran red line drew jeers from liberals and even Members of Congress. Sen. Barbara Boxer (D-CA) upbraided Netanyahu for interjecting himself in American politics. AIPAC took notice, e-mailing its members last week with articles on Obama’s refusal to lower his threshold for war and Netanyahu’s denials of interference. The debate seemed, for now, over, with Obama victorious. Then this week, Majority Leader Reid surprised everyone by re-introducing the Graham resolution.
