The UK and France had a lot of experience of running colonial empires, and had devised a recipe for establishing puppet states. You carved up the blank areas on the map, deliberately cutting across tribal/national boundaries, to establish zones with a 70/25/5 percentage split. The 70% majority were to be ruled and policed by representatives drawn from the 25% minority, armed with clubs and possibly rifles, while the 5% of imperial merchants and administrators enforced colonial rule over the 25%ers with machine guns and gunboats.
