The Finns only fought against the Soviets. The Finnish Russian War actually began before WW2 broke out with a Soviet invasion of Finland. Although the Finns were vastly outnumbered they and the Finnish winter gave the Soviets a severe ass kicking. Peace broke out between them in 1940 I think but the war resumed after the German invasion of USSR. The Finns were only allied with Germany out of necessity, the lesser of two evils to them. You have to remember that the Soviets just finished grabbing nearly half of Poland in concert with the Germans, a fact seldom mentioned in discussions of Germany invading Poland. Plus Latvia, Estonia and Lithuania, old Stalin had ambitions of his own.
