WHO SAYS DEMOCRACIES DON'T FIGHT?
Seldom if ever has the hostility between academics and the U.S. president been so pronounced. Of course, political scientists always seem to complain about the occupant of the White House, and Republicans fare worse than Democrats: Herbert Hoover was called callous, Dwight Eisenhower a dunce, Richard Nixon evil, Ronald Reagan dangerous, and George H.W. Bush out of touch. But professors have consigned George W. Bush to a special circle of their presidential hell. And the White House seems to return the sentiment.
According to the academics, Bush's chief transgressions have had to do with foreign policy, especially the Iraq war -- a mess that could have been avoided if only the president and his advisers had paid more attention to those who devote their lives to studying international relations.
The irony of this argument is that few other presidents -- certainly none since Woodrow Wilson, a former president of the American Political Science Association, scribbled away in the Oval Office -- have tied their foreign policies more explicitly to the work of social science. The defining act of Bush's presidency was grounded in a theory that the political scientist Jack Levy once declared was "as close as anything we have to an empirical law in international relations," namely, that democracies do not fight one another.
The theory, which originated in the work of the eighteenth-century philosopher Immanuel Kant and was refined in the 1970s and 1980s by several researchers working independently, has, since the 1990s, been one of the hottest research areas in international relations. Although some skeptics remain and no one agrees about why exactly it works, most academics now share the belief that democracies have indeed made a separate peace. What is more, much research suggests that they are also unusually likely to sign and honor international agreements and to become economically interdependent.
The administrations of Presidents George H.W. Bush and Bill Clinton made frequent appeals to the theory in public,
