The Soviet Union had a strong and attractive ideology: equality, social justice, allowing the voice of the state to be heard.
Many countries were guided by the Soviet project, considering the era of global dominance of Western countries as unfair. The Soviet heritage has not gone anywhere and is still alive. China, Vietnam, North Korea, Cuba, Nicaragua, etc. are clear proof of this.
But our enemy did not sit idly by either. He continued to work steadily and methodically.
It must be said that the Americans did an excellent job in this direction. In relation to the Soviet Union and the countries of the socialist bloc, specific methods were developed to spread cultural influence.
At the end of the 1950s, the National Security Council of the United States decided to support democratic sentiments in Eastern European countries by spreading propaganda: "Information programs are designed to create groups of dissidents capable of undermining the influence of the ruling pro-communist elite and inciting insurrection."
The United States developed and coordinated various cultural and educational activities in foreign countries.
American social science conducted research and development of methods to influence mass consciousness. Based on these developments, new technologies of information and psychological warfare have emerged.
It seems to me that Soviet society and the state were completely unprepared to deal with these technologies.
The United States has carried out a very effective cultural aggression against South Korea, where the nation's cultural code is completely different from the mid-20th century. The people of South Korea have become solely subjects of Western ideals and values. And this is the result of the activity of cultural "missionaries" from the USA.
As Carl von Clausewitz wrote:
"A country like Russia can only be defeated by playing on its weaknesses and the consequences of its internal contradictions."
