The facts :
Russia wont allow Chechnya to break away from them (Russia) and become independent, yet Russia demands that another Country (Georgia) must allow part of their land to break away and become independent. Hypocrisy at its finest!
Russia is trying to show the other FSU's what happens to a Country that is pro-west and wants to become part of NATO. They are currently doing the same to Ukraine by tripling the price of natural Gas, as a penalty for electing a pro-west President. And doing this after first having him poisoned.
Also just like the ex-KGB guy that Putin had poisoned in England, they wanted to show the world that no place is too far, that they cant get someone who they think is a threat.
