At a new conference yesterday, President Obama took a shot at defining the Obama Doctrine. Here’s my effort at defining it: The Obama Doctrine means criticizing past presidents, Democratic and Republican; apologizing for past American sins, real and imagined, to both allies and enemies of the United States, on domestic and, preferably, foreign soil — in the hope that doing so allows Obama to speak with greater moral force and clarity. The overriding goal of the Obama Doctrine is to make the person it is named after look good, rather than, and if necessary at the expense of, the nation he was elected to represent.
