What was the meaning of the idea of new political thinking?

The meaning of the idea was to change ideology and reject the previous ideas of Marxism-Leninism. Now, universal human values, and not state, national or class values, were at the forefront. From that moment on, a rethinking of history began, as well as the significance of the party in the life of the state, which led to a split among the supporters of perestroika and ultimately, according to historians, led to the collapse of the Soviet Union.
