"Martin Van Buren does not belong on anybody's list of great presidents, but he certainly belongs at the top of a sublist ranking presidents for diplomacy. Not only did he keep America out of war, but he did it twice, first with Mexico and then with England. Historians tend to glorify strong presidents, and nothing makes a president stronger than being a wartime leader. In a 1961 collection of scholarly articles on "America's Ten Greatest Presidents," for instance, half the presidents were men who had led the country into war. Yet managing to keep out of war can sometimes be an even greater achievement than rattling the war drums."
