Soviet Union under Stalin was an evil empire
On April, 25th, 1920 — Poland without declaration of war has attacked Russia which is bleeding profusely in civil war, and under the Riga contract has appropriated a part of the Ukrainian and Belorussian earths.In October, 1920 the Polish armies have grasped Vilno and Vilensky area at Lithuania, inconsiderately having broken the Suvalksky contract.

As a result by October, 1921 to Poland the considerable part of the Top Silesia from 80 % of all industry and the basic part of coal stocks has departed.
In October, 1938 Poland has attacked Czechoslovakia, having snipped off at last Teshinsky area where lived 80 thousand Poles and 120 thousand Czechs.

By the way, with Hitler's fascist mode the Polish management long time was in rather good fellowship, having concluded the non-aggression pact in 1934. When Hitler 1938 carried out on March, 11-12th annex Austria, Warsaw has tried to do the same with Lithuania (which called precisely «the Polish Austria»). On March, 15th, 1938 in Warsaw and Vilno have passed the Antilithuanian demonstrations under the general slogan «Forward on Kovno!» (To Kaunas — capital of Lithuania of that time). To Lithuania the ultimatum has been delivered, and to the Lithuanian border is concentrated over 100 thousand Polish armies. And only the position of the USSR and France has kept Poland from military intrusion.
