In assessing the progress of the revolution in Iran, it might be useful to recall how other revolutions of the 20th century fared at the 30-year interval. Using their commencement rather than the actual seizure of power as the baseline, the 30th anniversaries of major 20th century revolutions were 1940 for Mexico, 1947 for the Soviet Union, 1964 for China (using the “Long March” as the year), 1975 for Vietnam, 1983 for Cuba (dating its beginning with the attack on the Moncada Barracks), 1984 for Algeria, and 2008 for Nicaragua.
