Matt Welch dislikes Anne-Marie Slaughter's op-ed (gated) on Libya:

Slaughter and other Obama defenders are refusing to engage the arguments that their opponents have actually been using. Namely, that it is the Congress, not the president, that has the power to declare war; that the War Powers Act additionally requires the president to cease "hostilities" within 60 days of undeclared war absent congressional authorization; and that the president disregarded the advice of his own Office of Legal Counsel (and flagrantly reversed his campaign promise of "no more ignoring the law when it is inconvenient") by zooming through the 60-day deadline without a second look back. You may recall similar concern over such constitutional contortionism from back in the dark days of George W. Bush, when it was frequently evinced by the likes of…Anne-Marie Slaughter. Here she is in November 2005, co-authoring a Washington Post op-ed entitled–wait for it!–"No More Blank-Check Wars."

Slaughter tweets a response at Welch. Matt Steinglass is on her side. Elias Isquith bemoans the reliance on counterfactuals in her op-ed and the Libya debate more broadly.
