Communism can't ever be achived through Revolution

it’s so easy to change the government, but it’s so hard to change the people. The problem with communism is that it relies on the idea that people will be willing to work for the common good, but in reality, people are selfish and will always put their own interests first. Even if a revolution were to succeed. the outside govevrment will fund military and economic forces to destabilize the new government, and the people will eventually turn against it. The only way to achieve communism is through gradual change, not through a sudden revolution. It requires a fundamental shift in the way people think and behave, and that can only be achieved through education and cultural change over time.
