Adolf Hitler was well aware that Stalin was on his way to invade Europe. Kirill Meretskov in 1940, revealed that Stalin was preparing to invade Western Europe in July 1941 in a massive invasion called Operatsia Groza (“Operation Thunderstorm”). It is dated 18 September 1940, three months before the German “Operation Barbarossa” was signed. Adolf Hitler viewed communism as a poison to Europe and decided his life’s purpose was to root out and destroy it. The Germans had nothing against the Russians as a people, but instead against communism. Source: Lord Of War
