Professor Rostow's current book, Toward Managed Peace, argued that our need actively to pursue our national-security interests had by no means evaporated with the end of the Cold War. The events of the day before this taping--Boris Yeltsin had dismissed the Russian Duma--certainly bore him out. This thoughtful discussion ranges from the current fiasco in Yugoslavia--where neither the United Nations nor NATO was able to put an end to Slobodan Milosevic's "ethnic cleansing"--to "the major diplomatic mistake of the 20th century--and that's a field that has a great many major diplomatic mistakes ... : the 1918-1919-1920 period in Russia when we should have helped, obviously on a very large scale, the promising new democratic regime of Prince Lvov and Kerensky to succeed. The Allies, exhausted by the First War, made a few feeble gestures and then retreated and allowed this cancerous development of the Soviet regime to take place."
