RED ARMY!!! REMOVE DUBCEK FROM OFFICE! SEIZE CZECHOSLOVAKIA!
Thank you mighty Stalin! I will undo all reforms and see to the death of all democratic supporters!
Gustav Husak, you're a fine communist leader, you can take control after the invasion!
650,000 troops entered Czechoslovakia. Thousands of tanks came with them. All military fighting was ended quickly. Scattered rebel fighting lasted longer. Dubcek was removed and then later sent back after he was deemed no longer deadly to the USSR.
Scattered rebel fighting lasted for 8 months, the Soviets predicated that fighting would end in four days. Most remained non-violent because Dubcek did not want them to get slaughtered.
Prague Spring ended in a decisive USSR victory. Communism prevailed until they finally collapsed.
