"The Victims of Communism Memorial Foundation’s mission is to educate future generations about the ideology, history, and legacy of communism and to advocate for the freedom of those still held captive by communist regimes.

Positive attitudes toward communism and socialism are at an all-time high in the United States. We have a solemn obligation to expose the lies of Marxism for the naïve who say they are willing to give collectivism another chance. New generations need to confront the reality of Marxism in practice. Socialism is not a kind, humane philosophy. Marxist socialism is the deadliest ideology in history. In the 21st century, we have an opportunity to learn from the 20th century and rededicate our free society based on individual liberty, free enterprise, the rule of law, democratic self-government, and human rights."
