At beginning of WWW2, USSR had pretty good position: thousands of tanks, millions of tons of ammunition, million army, powerful ally (Germany). USSR attacked Finland at winter to prevent invasion of France & Britain via Norway and Finland to attack Leningrad. It was risky move, lot of soldiers of Red Army died because of cold, but USSR won. At beginning 1941, USSR waited for beginning of Britain bombing of Baku, to start invasion to East (to attack British military bases) with help of Germany, and then to conquer Britain islands. Everything was perfect until 22 June 1941.
