If I recall my history correctly, this issue was already settled by an agreement with the Soviet forces approaching from the East, Was it Potsdam?
Anyways we were probly better off since the Soviets took horrendous losses taking the capitol,
I remember reading figures in excess of 350,000.
Am sure some friendly FReeper will correct me if I am wrong/
Yalta .... but even Churchill wanted Ike to take Berlin.
