On 10 December 1981, in the face of Poland's Solidarity movement, Andropov, along with Soviet Second Secretary Mikhail Suslov and Polish First Secretary Wojciech Jaruzelski, persuaded Brezhnev that it would be counterproductive for the Soviet Union to invade Poland by repeating the 1968 Warsaw Pact invasion of Czechoslovakia to suppress the Prague Spring. This effectively marked the end of the Brezhnev Doctrine.
