Excuse me Lepus, but... the Chechen Nation? To the best of my knowledge, the Chechens have never been a nation. They have occupied a certain section of country for quite some time but have always been under the governance of other, more powerful countries. The Chechens are a nation only in their own minds. You might also speak of the Pashtun "Nation" or the Kurdish "Nation".
As geo-political entities, they do not exist. Whether or not they SHOULD exist is another matter altogether.
