The Russians 'tore the heart out of the German army.' Do you agree with Winston Churchill?

Completely!The Russians were the ones who took on the bulk of the German Whermacht and made a full retaliation from it which crushed Germany's best soldiers and left the Germans with no useful defenses against the Red Army.When Hitler removed Manstein(the commander of the Germans in Russia),it was only a matter of time before the Reds would eventually step into Berlin.
