In the midst of President Harry Truman’s controversial firing of General Douglas MacArthur during the Korean War, Air Force General George Kenny, who brilliantly led MacArthur’s air force in the Southwest Pacific in World War II, wrote that when the histories of the Korean War are written, they will "add still more to the luster of MacArthur's reputation as a military leader." General Kenny was wrong about historians, who have largely taken Truman’s side in the debate over how to deal with China’s entry into the war. But in a larger geopolitical sense, General Kenny was right. China’s rise in the 21st century and its challenge to America’s global preeminence have vindicated MacArthur.
