Adolf Hitler, Führer of Germany, writing in a letter to Benito Mussolini, Il Duce of Italy (25 August 1939).
The relationship of Germany to Poland, as a result of the policies of England, has become more unsatisfactory since spring and in the last few weeks the position has become simply unbearable. The reports about the persecution of the Germans in the border areas are not invented press reports but represent only a fraction of the terrible truth. The current policy of Poland has brought about a complete standstill in Danzig’s entire economic life for the past several weeks and would, if it were continued, destroy the city.
The readiness on the part of the Soviet government to negotiate with Germany has made it possible for me to send my Foreign Minister to Moscow for the conclusion of a treaty which is the most extensive non-aggression pact in existence and whose text will be made public.

They rapidly agreed on a non-aggression pact. If one partner went to war, the other promised to remain neutral.

Stalin not only had peace but a promise of spheres of influence that Britain and France had denied him …
In a letter to Hitler, [British Prime Minister] Chamberlain vowed that, despite the Nazi–Soviet Pact, Britain would not step down from its obligations to Poland. Chamberlain pointed out to Hitler that war between Britain and Germany would be a disaster and that there was nothing between Poland and Germany that could not be settled peacefully. Chamberlain recommended a truce on both sides …
Hitler telephoned Mussolini to tell him that an attack on Poland was imminent and that he needed the help that Mussolini had promised in the Pact of Steel. Mussolini had to admit that Italy could not go to war unless it received urgently needed supplies …

Hitler had ensured Stalin’s neutrality so he could attack Poland. Hitler also hoped that Britain would remain neutral and not become embroiled in any war between Germany and Poland so on 1 September 1939 Germany attacked Poland.
