British rule in the Dominion countries went like this: exterminate or wholly subjugate the natives, then flood the place with whiteys from Blighty. Same thing happened in the US, but they took the subjugation a step further into crusade territory with 'manifest destiny'. In effect, Britain was able to transplant its culture and laws directly in these places.

British rule in India couldn't do this - half a billion people is a bit too many to simply overrun. Instead they played factions against each other, one trick being to give a smaller faction superior arms, they keep the peace and a slice of the pie, but are wholly dependent on the supply of arms. British rule in India was a massively different beast to the Dominion countries.
