It is the hypocrisy I am pointing out, To argue they have any right to that land due that some old historical claim which is subjective because other people where they before thek is moronic.
If you wish to apply that standard, Russia must give Sevas back to China, must give the kirls back the Japan and must surrender Kalin to Germany, Crimea to Greece or Turkey etc, list goes on
So the situation is that Russia and Armenia and Azerbaijan all do not say that NK is Armenian land... there doesn't seem to be any problem with this by any side....
So what is the problem... well Russia and Armenia and the people of NK don't want Azerbaijan to come in and claim the land for themselves and kill the locals whom they see as foreigner.
It is very much the same as the situation in the Ukraine... Ukrainians living in the East of the country spoke Russian but they never wanted to join Russia until Kiev had shelled and bombed and shot and murdered them for 8 years.
Russia hasn't spend the better part of the last decade claiming these people are Russians and it would not be Russias place to tell them who they are... they had to decide for themselves and they have had a referendum and decided to join the Russian Federation and become Russians because that was their best option for the future.
The people living in the NK should have a referendum and perhaps decide on independence if no one accepts them as being part of Armenia then let them become an independent state... which they must have been for all this time anyway.
What you are missing is that international law basically allows the people on the land to decide... outside powers should not get to choose... even if they are the US or UK or whatever.
Of course letting a majority decide does not give them the right to abuse a minority within their borders, or to ship them out or ship other people in to change the results of any referendum.
Of course conflicts change things... the people of the Falklands are mostly British and see themselves and their culture as British... it would be interesting to know if any Argentinians have every tried to move there and what response they got from the locals... I suspect they would not be made welcome. In South Ossetia and Abkhazia there was conflict and Georgians living in those regions had to leave which of course will change any results you might get from any referendum... but of course allowing them to go back and they will take advantage of that and move a huge number of Georgians back into those regions to take them over a bit like the Albanians did in Kosovo.
The fact is that there is nothing completely fair about this, but Russia is there to try to stop two or three groups from killing each other... as opposed to a western intervention which normally picks a side and calls the other side the enemy and tries to kill the designated enemy while claiming the side they are fighting for are the innocent victims... which normally means they have promised oil and resource contracts to the US for after the war is over.
And that's all it takes. You don't even need to gain most of the votes, just enough to dispute the result and gather the crowd with your allegations of election fraud supported by the Western media apparatus.
The irony is that the countries doing the most to undermine democracy and peoples choice is the so called democratic west.
