I'd always wondered what a universe would be like where GB didn't really get overly involved in WWI and adopted a more distanced and nuanced role from the sidelines; and then gave dominion status to India (intact and without partition) sometime in the 30's.

Consolidation rather than desperation....no Uncle Adolph and perhaps no USSR, but a German dominated Europe and London and Berlin competing for dominance. Don't quite know what would need to change, perhaps too much, but I've an idea for a novel lurking somewhere in there.
