Leaving the "crush the russians" out and the hatred of the Jews,could the Allies even have got along with Germany. Ike already had his hands full with Patton and Monty's bickering. Now he'd have the German Generals as well. And the language now would be a problem.

Would Blitzkreig exist? Would Tiger tanks exist? More bickering over which tank should be produced? Might have been interesting[imo] to see what kind of tank was produced had they combined ideas.
Not trying to rehash the teaming up on the Russians, just wondering how the two could have worked together as allies.
