I never said the target is for Germany to overwhelm the Soviets and beat them by '42-'43, it's probably meant to do it by '45 at the earliest in most cases.
In my experience (which, granted, is not very extensive, as I haven't played without EAI since a few weeks after 1.8 was released), that target is being achieved in the current patch.
As the US you have a good amount of time to build up, while you bide your time on fronts which naturally require less troops gradually scaling up as you progress, going for the historical route with Operation Torch, where low supply automatically limits number of troops (and probably having to invade from Sudan into Egypt as well because the British can't hold the Suez for their lives), then going for Italy, where the narrow peninsula and defensive terrain makes it easy to hold with comparatively fewer troops if you're quick enough and don't give them enough time to reinforce, then culminating on a big European invasion.
That's another topic entirely, but I agree, the game needs to give you more control over you allies.
Requesting exp forces, though finicky, was a step in the right direction, but allies clogging up my airbases and not coordinating their navy for my invasions is really bad.
