How did Democrats and Republicans view

Cold War policy?

Republicans supported Woodrow Wilson's call for American entry into World War I in 1917, complaining only that he was too slow to go to war. Republicans in 1919 opposed his call for entry into the League of Nations. A majority supported the League with reservations; a minority opposed membership on any terms. Republicans sponsored world disarmament in the 1920s, and isolationism in the 1930s. Most Republicans staunchly opposed intervention in World War II until the Japanese attack on Pearl Harbor in 1941.

After the mid-1960s, Democrats increasingly tended to oppose larger military budgets, while Republicans more often favored them. This article presents evidence about the process through which this change took place. It identifies several developments in the domestic and international environments that may have contributed to this party switch and evaluates preliminary evidence about each of them.
