Yes sir. Old enemies often make the suitable allies as the French did for us in the Revolution.
The Soviets were Churchill’s nemesis until Hitler invaded Mother Rus in 1941. Then he said had Hitler invaded Hell, he would at least speak favorably of the Devil in the House of Commons.
The Germans were superior soldiers to not only the Russians, but they out killed Brits and Americans at a high rate also.
The more German soldiers fighting the Russians the better, anyone who would have turned down WWII German soldiers to use against their hated enemy the Russians, on their own soil, would have been nuts.
