And BTW, you are wrong in saying that historians consider Riga treaty as Polish victory. If u check Spanish, French or Italian wikies for instance, there is no mention of any Polish win. It's only in Poland historians claim that, because for Poles, Soviet-Polish war is basically only Vistula battle, however they don't emphisize on the fact that first attack was conducted by Poland, however Red Army got beaten Polish forces and tried to counter-attack after. The counter-attack failed. So peace treaty simply splitted Ukraine and Belarus. No win of Poland at all.
