"The Khalq’s seizure of power in Kabul was the last of the twentieth-century communist revolutions and demonstrated beyond peradventure that communism had no chance of surviving in power without resorting to massive repression. The Soviet comrades were frequently appalled by what they witnessed. They belonged to a generation which remembered the horrors of Stalin’s rule, and they could hardly believe the recklessness of Pol Pot, Mengistu Haile Mariam and Hafizullah Amin. These were revolutions led by men wilder than the early Bolsheviks, wilder even than Stalin and Mao. They attempted to solve problems of economics, administration, ethnicity and religion by surgical force. Their mayhem kicked up a storm of hatred for communism. Yet the gradualist approach of Salvador Allende was hardly more successful; his regime was hurtling towards economic disaster and political disintegration even before Pinochet struck. Communist revolutionary rule proved to be a passage down a cul-de-sac."
