The British spent the entire 1930s claiming that Britain and Nazi Germany will be a bulwark against communism and signed three pacts with Hitler which were all directly against the Soviet Union: the Four Powers Pact meant to exclude and isolate the Soviets, the Naval Agreement meant Germany could have a navy up 35% of the British navy meaning it wouldn’t threaten British empire but every country on the Baltic sea… i.e. the Soviet Union, and finally the Munich Betrayal which was understood to be a gesture of a “free hand” (British diplomat’s words not mine) for Hitler to go east.

In spite of these difficulties Lord Halifax and other members of the British Government were fully aware that the Fuhrer had not only achieved a great deal inside Germany herself, but that, by destroying Communism in his country, he had barred its road to Western Europe, and that Germany therefore could rightly be regarded as a bulwark of the West against Bolshevism

In spite of these difficulties Lord Halifax recognized that the Chancellor had not only performed great services in Germany, but also, as he would no doubt feel, had been able by preventing the entry of Communism into his own country, to bar Its passage further West. The Prime Minister held the view that it should be possible to find a solution of out differences by an open exchange of views

When the Soviets liberated Germany they were able to get a huge cache of British diplomatic documents. The Soviets released the above book and Documents And Materials Relating To The Eve Of The Second World War Vol. 2 full to the brim of diplomats praising Nazi Germany as a twin pillar alongside Britain stopping communism.
