Wheather there were any transcripts of Stalin having written a grand plan to conquer and instill Communism into Western Europe is up for speculation and Carl W Schwamberger and Za Rodinu have said there were none, so i'll go along with that, but if Stalin had signed a peace treaty with Germany in 1942, Lend Lease i agree that would end. But the Soviets still have their industry and oilfields intact. And can purchase war materiel with goods and oil.

And to finish off we have a stalemate between Germany and Britain but one theatre of war becomes vital to Britain and the Axis and that is North Africa, Hitler could effectively withdraw the four divisions (1 panzer, 1 panzer-grenadier and 2 infantry) as Rommel wanted to defeat the British. If the German and Italian forces conquered North Africa and seize the Suez then it makes it more easier for the Axis to annexe the entire Med Sea.

Britain would have to seek either direct US military aid by deployment of US Forces in Britain and if the US refuse, Britain again either has to come to terms with Germany by an Armistice or Surrender, and Surrender is not an option.
