non-aggression pact Molotov–Ribbentrop Pact Joseph Stalin Pact of Steel Germany de Britain
This plan required tacit Soviet support, and the non-aggression pact (the Molotov–Ribbentrop Pact) between Germany and the Soviet Union, led by Joseph Stalin, included a secret agreement to partition Poland between the two countries. Contrary to Ribbentrop's prediction that Britain would sever Anglo-Polish ties, Britain and Poland signed the Anglo-Polish alliance on 25 August 1939. This, along with news from Italy that Mussolini would not honour the Pact of Steel, prompted Hitler to postpone the attack on Poland from 25 August to 1 September. Hitler unsuccessfully tried to manoeuvre the British into neutrality by offering them a non-aggression guarantee on 25 August; he then instructed Ribbentrop to present a last-minute peace plan with an impossibly short time limit in an effort to blame the imminent war on British and Polish inaction.
