"General Wojciech Jaruzelski, the Minister of Defence since 1968 and thus a major Warsaw Pact figure, became Prime Minister in February 1981 and First Secretary of the Polish Communist Party in October 1981. Jaruzelski had taken part in operations against anti-Communist resistance fighters in the late 1940s, had led Poland’s contribution to the invasion of Czechoslovakia in 1968, and had been in command when Polish troops shot striking shipyard workers in 1970. Jaruzelski claimed he had opposed the last operation and he sought a peaceful settlement with Solidarity, but serious economic problems continued to create discontent in Poland and to lead to criticism of the government. Meanwhile, the Soviet Union pressed Jaruzelski to come out in defence of Communism. This pressure indicated that any meaningful change in the Soviet bloc would have to come from Moscow, and thus underlined the subsequent importance of Gorbachev’s stance."
