some peoples have power to think about their nations.
But "peoples" is a proper word, and this is arguably a context in which it could be used - ie. with 'nations'. "The peoples of some nations have more power than others."Note that the plural of "person" is "people", not "peoples".
some peoples have power to think about their nations.
what you mean is "some people have rights to think of their nations", isn't it?
