It is ungrateful to bash the US for taking two years fighting in the Pacific before we could start another front. If it was so easy why didn't Russia fight on two fronts?
Don't forget The CBI (China-Burma-India) theater as well.
That was well under way before we even thought about europe.
That is not the point. The point is simply that Russia was fighting for its life and lost far more people and treasure in the war than we did. And by doing that they bought England and us time (as we were preoccupied in the Pacific and building arms and armies)
Yes, we were also fighting desperately, too. We had hundreds of thousands of casualties in the Pacific.
It doesn't denigrate what we did to acknowledge what they did.
