As we in the United States celebrate Memorial Day, I noticed an article by James Bovard on the relevance of democracies and whether they make war on each other or not. My college political science professors liked to say that democracies don't go to war against each other. Democracy-building has been a core tenet of American foreign policy since at least the days of Woodrow Wilson. As Bovard makes clear in his excellent article, democracies often do fight each other and have done so for hundreds of years, for a variety of reason.
The point is not to denigrate democracy as a means of political organization, but to encourage the American people to question their political leaders the next time they preach "spreading democracy" as a foreign policy goal.
