If talked about without hatred and overnationalistic feelings the battle of Warzaw 1920 certanly is a valid topic I think. Krook gets some support from J.F.C. Fuller (1878-1966). He lists this battle as one of the worlds most important in his "Decisive battles of the western world". Fuller was both a soldier (one of the fathers and thinkers of armoured warfare) and a historian.

Maybe the russian army alone could not have conquered europe had they won this battle but with the help of a victory most certanly Poland was gone and central europe (germany for instance) would be open to propaganda, influence and revolution (this was very likely to happen) that very possible would not have stopped until it hit the atlantic.
