At one point, I mentioned the slogan President Obama recently coined to describe his foreign-policy doctrine: “Don’t do stupid shit” (an expression often rendered as “Don’t do stupid stuff” in less-than-private encounters).

This is what Clinton said about Obama’s slogan: “Great nations need organizing principles, and ‘Don’t do stupid stuff’ is not an organizing principle.”

She softened the blow by noting that Obama was “trying to communicate to the American people that he’s not going to do something crazy,” but she repeatedly suggested that the U.S. sometimes appears to be withdrawing from the world stage.
