In early 1920, Soviet–Polish tensions eventually led to the Polish–Soviet War. In the run-up and during the war, Trotsky argued that the Red Army was exhausted and the Soviet government should sign a peace treaty with Poland as soon as possible. He did not believe that the Red Army would find much support in Poland proper. Lenin later wrote that he and other Bolshevik leaders believed the Red Army's successes in the Russian Civil War and against the Poles meant "The defensive period of the war with worldwide imperialism was over, and we could, and had the obligation to, exploit the military situation to launch an offensive war."
