How did Russia win world war 2?

the Soviet Union contributed the most in destroying the third Reich. The Eastern Front was the biggest front and the majority of the Nazi Force were sittuated there. In fact they played such a big role, that many experts agree that if there wasnt a Western Front, it would still hae only been a matter of Tim for the Soviet Union to win.

Ps: Russia was the first country to enter Berlin, it was the country to demolish the reichstag and it still has the trophy eagle, from the reichstag un the Moscow WA museum.
