thereafter attempting to impose himself and his system upon the world in the process. Anti-communism In Hitler's mind, communism was a major enemy of Germany, an enemy he often mentions in Mein Kampf. During the trial for his involvement in the Beer Hall Putsch, Hitler claimed that his singular goal was to assist the German government in "fighting Marxism". Marxism, Bolshevism, and communism were interchangeable terms for Hitler as evidenced by their use in Mein Kampf: 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. In 1939, Hitler told the Swiss Commissioner to the League of Nations Carl Burckhardt that everything he was undertaking was "directed against Russia" and that "if those in the West are too stupid or too blind to understand this, then I shall be forced to come to an understanding with the Russians to beat the West, and then, after its defeat, turn with all my concerted force against the Soviet Union". When Hitler finally ordered the attack against the Soviet Union, it was the fulfillment of his ultimate goal and the most important campaign in his estimation, as it comprised a struggle of "the chosen Aryan people against Jewish Bolsheviks". Biographer Alan Bullock avows Hitler "laid great stress" on the need to concentrate on a single enemy, an enemy he lumps together as "Marxism and the Jew". Shortly in the wake of the Commissar Order, a directive pursuant to the German invasion of the Soviet Union, SS Deputy Reinhard Heydrich informed the SS of Hitler's geopolitical philosophy which conflated Bolshevism and Jews, writing that "eastern Jewry is the intellectual reservoir of Bolshevism and in the Führer's view must therefore be annihilated". Considering the eventual Nazi invasion of the Soviet Union (Operation Barbarossa), no additional inducements are really requisite concerning Hitler's hatred of communism, particularly since the Nazi persecution and extermination of these groups was not
