 In April, Dubček launched an "Action Program" of liberalizations, which included increasing freedom of the press, freedom of speech and freedom of movement, along with an economic emphasis on consumer goods, the possibility of a multiparty government and limiting the power of the secret police.Initial reaction within the Eastern Bloc was mixed, with Hungary's János Kádár expressing support, while Soviet leader Leonid Brezhnev and others grew concerned about Dubček's reforms, which they feared might weaken the Eastern Bloc's position during the Cold War.On 3 August, representatives from the Soviet Union, East Germany, Poland, Hungary, Bulgaria, and Czechoslovakia met in Bratislava and signed the Bratislava Declaration, which affirmed unshakable fidelity to Marxism–Leninism and proletarian internationalism and declared an implacable struggle against "bourgeois" ideology and all "anti-socialist" forces.
