After the Hungarian uprising, Yugoslavia’s relations with the USSR cooled significantly in the 1957-1960 period. It was during this time that Hoxha was able to come to the defense of Stalin at the Plenum of the Central Committee of the Party of Labour of Albania on February 13, 1957.
“But it was Hoxha who in his speech to the Plenum of the Central Committee of the [Albanian Party of Labour] on February 13, 1957, took up the defense of Stalin. After having defended the Soviet Union for her action in suppressing the Hungarian revolt and denouncing Yugoslav ‘revisionism,’ he [Hoxha] declared that all campaigns which the imperialists and revisionists had started against Marxism-Leninism, against communism, were carried out under cover of struggles against ‘Stalinism.’
‘We are not in agreement with all those who attempt to discount the entire positive revolutionary side of Stalin, as experience, and who see only the black side of it… As is known, J. V. Stalin was a great Marxist. After Lenin it was he who protected Marxism-Leninism on all sides from revisionism and contributed greatly to the further development of science. Great merits are due to him in the preparation and development of the October Revolution, in the building of the first socialist state, in the historic victory over the invading fascists, in the development of the international communist and workers’ movement. For all these deeds Stalin enjoyed great authority, not only in the Soviet Union but throughout the world… Stalin was never mistaken in such questions as the protection of the interests of the working class and of Marxist-Leninist theory, the fight against imperialism and against the other enemies of socialism. He was and remains an exemplary figure.'”
