Why is it important that colonial people gain their independence?

Colonial nations are not mere offshoots of the

nations that gave birth to them. The geography, ecology, history of the continent forged them as original identities, like it did for the indigenous when they came millenia ago. To remove them from this context is to remove them from what made their identities in the first place. It's to such a point you can see very similar behaviours and interests in some circumstances.
