Nationalism versus Peace

Paul Krugman has good column today on the threat of nationalism to globalization.

Shortly
before World War I another British author, Norman Angell, published a
famous book titled “The Great Illusion,” in which he argued that war
had become obsolete, that in the modern industrial era even military
victors lose far more than they gain. He was right – but wars kept
happening anyway….

…the belief that economic rationality always prevents war is an
equally great illusion. And today’s high degree of global economic
interdependence, which can be sustained only if all major governments
act sensibly, is more fragile than we imagine.
