"As a result of the Soviet hopes of world revolution or, at least, ideological expansion into Central Europe, the Polish victories near Warsaw between 16 and 25 August 1920 were a key incident in the Cold War. The Battle of Warsaw ended the drive west by the Soviets, a drive which had already led them to capture the cities of Minsk and Vilnius the previous month. Had the Soviets succeeded in 1920 and established a sister republic in Poland, on the model of the French Revolutionaries in Italy, Switzerland and the Netherlands, then Communism would have had an opportunity to become more strongly grounded."
