Stalin always pressed England and the US to open another front during the 1940s as German forces were concentrating to deepen in the Soviet territory.
He believed the Western allies were on purpose to profit from the weakening of the USSR as it fought against Nazi Germany.
The delayed had enabled Nazis to redirect manpower to the Eastern front.
Stalin was annoyed since he believed the US and Britain delayed to open the second front against German troops in the West, and demanded a buffer formed from Baltic nations and Poland after the war.
