Later in his seminal tome, Hitler advocated for "the destruction of Marxism in all its shapes and forms". According to Hitler, Marxism was a Jewish strategy to subjugate Germany and the world and saw Marxism as a mental and political form of slavery. From Hitler's vantage point, Bolsheviks existed to serve "Jewish international finance". When the British tried negotiating with Hitler in 1935 by including Germany in the extension of the Locarno Pact, he rejected their offer and instead assured them that German rearmament was important in safeguarding Europe against communism, a move which clearly showed his anti-communist proclivities.
