Who Was the Best Foreign Policy President?

In less than two weeks, President Barack Obama and Republican nominee Mitt Romney will square off in the first of a series of presidential debates that will include foreign policy. But who should they be drawing their inspiration from? And whose examples should they be avoiding?

Global Public Square asked a group of historians and commentators for their take on the most successful and least successful U.S. presidents, from a foreign policy point of view. Here, we feature their picks of the best, and on Friday, we'll highlight those considered the least successful. (All views expressed here are, of course, the writers' own.) Agree or disagree?
