In a recent commentary for the Austin American-Statesman, Bonner Means Baker fellow Joe Barnes questions whether the foreign policies of a second-term President Barack Obama and a first-term President Mitt Romney would differ in any significant way.

While "we can assume that there will be continuity in broad aspects of U.S. foreign policy," Barnes writes, "this is true of all changes in U.S. administrations. Our interests abroad are varied. Our commitments are long-standing. The scope for dramatic change is limited."

That said, Barnes touches on a number of areas where "a Romney administration might mark -- and the 'might' bears stressing -- a significant change from the current one," including China, Russia and the Arab-Israeli dispute. The policies of the two candidates are likely to be very similar in one important area: Afghanistan, Barnes adds. Romney has "called for ending the U.S. combat presence there in 2014, a position not very different from Obama"s."
