Politically: Gorbachev's "new thinking" caused great ideological confusion in the whole Soviet Union and Eastern Europe. He believes that rights belong to everyone, no matter what class he is; This runs counter to the dictatorship of the proletariat. The consequence of "new thinking" is that the * * * production party in the Soviet Union and Eastern Europe lost its position as the ruling party, thus destroying the socialist system on the superstructure.

Economically, the Soviet Union and Eastern Europe only paid attention to heavy industry for a long time, ignoring light industry and agriculture, and the economic system was too rigid to improve people's living standards. In addition, in the late Cold War, the United States deliberately depressed oil prices and gold prices in order to bring down the Soviet Union. At that time, oil and gold exports were the main foreign exchange sources of the Soviet Union, which led to the shortage of funds in the Soviet Union and had to rely on loans to maintain it. This has created opportunities for international speculative capital. They bought Soviet government bonds in large quantities, and then sold them almost at the same time in a very short time, which led to the serious depreciation of 1990 rubles, the hyperinflation of the Soviet Union, and finally the collapse of the Soviet economy.

Militarily: the long-term consumption with the United States in the cold war eventually became a heavy burden on the country, which accelerated the disintegration of the Soviet Union to some extent.

Courses:

1. It is urgent to ensure domestic political stability, especially for a big country like China.

2. Improve the national financial firewall and be alert to foreign financial attacks.

3. Adjust the industrial structure and effectively improve people's living standards.

Military forces should serve the country's economic construction, not become its economic burden.

The above is my humble opinion, I hope it will help you.
