said could be dispatched, if Polish objections to the Red Army crossing its territory could first be overcome.
But the British and French side - briefed by their governments to talk, but not authorised to commit to binding deals - did not respond to the Soviet offer…
After trying and failing to get the Western capitalist powers to join the Soviet Union in a collective security alliance against Nazi Germany, and witnessing country after country being ceded, it became clear to Soviet leadership that war was inevitable-- and Poland was next.
Unfortunately, there was a widespread belief in Poland that Jews were overrepresented in the Soviet government and that the Soviet Union was being controlled by Jewish Communists. This conspiracy theory (Judeo-Bolshevism) was fueled by anti-Semitic propaganda that was prevalent in Poland at the time. The Polish government was strongly anti-Communist and had been actively involved in suppressing Communist movements in Poland and other parts of Europe. Furthermore, the Polish government believed that it could rely on the support of Britain and France in the event of a conflict with Nazi Germany. The Polish government had signed a mutual defense pact with Britain in March 1939, and believed that this would deter Germany from attacking Poland.
Seeing the writing on the wall, the Soviet Union made the difficult decision to do what it felt it needed to do to survive the coming conflict. At the time of the Molotov-Ribbentrop Pact’s signing (August 1939), the Soviet Union was facing significant military pressure from the West, particularly from Britain and France, which were seeking to isolate the Soviet Union and undermine its influence in Europe. The Soviet Union saw the Pact as a way to counterbalance this pressure and to gain more time to build up its military strength and prepare for the inevitable conflict with Nazi Germany, which began less than two years later in June 1941 (Operation Barbarossa).
