You want to know what was the secret weapon the USA and allies unleashed to fight and counter communism? The arts. Music, literature, film, and art are all mediums that helped erode communism as they showed another way of being. An openness, freedom, and inspirational way of being to help create change in the world. I have heard immigrants from oppressed countries in current day mention how they would privately watch American film to dream of another more open world. This must be maintained if we are planning to continue as a free society ourselves.
