Lie had been personally shaken by the post-war Soviet suppression of the social-democratic parties in Poland, Czechoslovakia and Hungary. He viewed Yugoslavia leader Josip Broz Tito as the "Martin Luther of communism" after Tito had openly defied the Soviet Union by chiselling out the Third Way. When the Soviets initiated a blockade of Yugoslavia following the Tito–Stalin split, Lie organized humanitarian aid-shipments from Norway. Another concern was that the Pro-Moscow Norwegian Communist Party (NKP) had was gaining support among leftist voters, with opinion polls showing an increase to 15.4%. As he put it :"It was voting based upon the myth of the Soviet Union as the land of peace and socialism - a myth which had to be broken down". It was during this period that Lie, with support from the trade union center set up significant and wide-ranging surveillance of Norwegian communists, (a practice later deemed illegal by a government committee, the Lund commission).
