Mikoyan was the only person in the Soviet leadership who raised his voice against coercive intervention into the political crisis in Hungary. It was to a large extent thanks to his position on the eve of the uprising in Hungary that a military action in Poland, affected by anti-Soviet and anti-socialist mood, was prevented. According to the author, the tragic mistake of Nagy lay in his decision to withdraw Hungary from the Warsaw Pact, which gave rise to a military solution to the crisis. Mikoyan's attempts to persuade his colleagues to seek an alternative variant were futile. He should be credited for his achievements in conducting negotiations with the Chinese Communist leadership enabling to delay Soviet-Chinese conflict and the second split in the international Communist movement (following the first Yugoslav-Soviet split in 1948–1953).
The author posits that A. Mikoyan should not be idealized, however, some of his ideas concerning foreign policy articulated in 1956 and practical steps strengthened the position of the Soviet Union as one of the world leading states.
