Democratization of the world order became the main outcome defeat of fascism. In Russia, this process from Khrushchev’s Thaw until post-Soviet reforms including all its flaws and regressions resulted in failure of totalitarianism; in Europe – in the fall of fascist, authoritarian regimes and establishment of social statehood; in “The Third World” – in the collapse of colonialism.
