The question implies that there are nations that deserve democracy and nations that don't deserve it. The former are some privileged peoples that enjoy all advantages of democracy and the latter are outcasts that are not able to do that. This reasoning is false because the premise is false. And this premise is that democracy is the best political system, which is implied by the meaning of the word "deserve". Actually, this isn't the case. Democracy is the best political system.
I'm a bit confused by what you're saying here. Is Democracy the best political system or not?
