Regardless of how a government treats its citizens, and what sorts of wars they start, their sovereignty must be protected. Their established democracy or citizenship should be given priority in this shifting global landscape. Too many countries are given low priority in terms of sovereignty and independence from superpowers. This should not be.
Chechnya is still part of Russia and shouldn't count on foreign military intervention unless the mother country wantonly kills ethnic Chechens. The problem is complicated--terror attacks in Russia are often blamed upon Chechen insurgents who want freedom. Ethnically, Chechnya may have a sovereign claim. However, foreign military units shouldn't get involved until bloodshed becomes more one-sided or if the violence spills over into another country.
