In this book, Hoxha criticizes some European communist parties that do not support Marxism-Leninism and Stalin. He explains why the communists couldn't win in West Europe (France, Italy, Spain) after/during the second world war. He also looks at the situation in Khrushev's Soviet Union and China and decides that both countries are revisionist or even not communist at all, as well as Yugoslavia, which is also accused of trying to sabotage Albanian socialism.
