So you think that Russia should be able to grab chunks of eastern ukraine wherre thers a majoriy speaking population? Id also be interested wher you think a country in the West has annexed another country on the basis that the majority population speak their language? Last time I think that happened was Germany 1939? If you look at the basis for this kind of action, youre essentially legitimising the naturalisation of countries. For instance, Tibet. How much longer before its majority chinese, and then thats Chinese territory right? You could rewrite the world map on that basis.
