I won't touch Ukrainian and Georgian part, but Chechnya is out of context here, honestly.
Carpet bombing cities is fine then? Not a threat at all, right?
Georgians? The ones who attacked the russian peace keepers in South Ossetia to ( as said by Saakashvili in person ) humiliate Putin!
Do tell, how does a country 'attack' itself? Russia is playing a dangerous game chipping away land from it's neighbors in the name of "protecting" ethnic Russians
