Same as otl, that war.

Geopolitically, the Brits are going to get involved against the Germans eventually. That was far from the only reason, just the best available. No net advantage, because the areas taken in the west in WWII during the first offensive are more or less going to counter the increased German forces in the east.

Come to think of it, mind, without that plan, however.... the Germans may not be so willing to go to war in the first place.
