Michael GorbachevAccording to his staff, his goal was “socialism with a human face”. The belief that communism could be reformed led him to risk fundamental changes. Soviet citizens were allowed to speak and demonstrate, open shops and travel abroad without fear of arrest. Gorbachev put an end to the Cold War, renounced the Marxist idea of class struggle as the driving force of history, and refused to intervene to save the communist regimes of Eastern Europe.
In the end, Gorbachev could neither save his own power nor create a democracy. He defeated totalitarianism but did not destroy it. He adhered to socialist beliefs and fought to preserve the ideological structure of the Soviet Union. When he was deposed on December 25, 1991, and the Soviet flag was raised over the Kremlin for the last time, the moral and legal vacuum he left in his wake created a criminal oligarchic regime in Russia that used terror to stay in power , and a full-scale war against Ukraine.
