Lawyee, the law system you're talking about and you're defending was created by the US and EU mostly, which means: 1) it was created by and for double-standards; 2) the US and EU use this system for interests of their own usually, neglecting the common to all mankind law that directly says: "Don't kill!".
In other words, if you or your friends are being shot by guys with a sub-machine gun, please try to explain them that, according to the law, they have no legal right to do so (or call to the UN to protect you).
The modern law and political systems are OBSOLETE because they don't solve current problems effectively at all.
Lawyee
Furthermore, if you say that there are many (maybe majority of) Russian citizens in the region, they have no right to decide about the form of the state, because they are not citizens of that state and do not have right of sovereignty which was conferred to Georgian state. In other words, they are foreigners on the territory of Georgia and have no political rights there (they have them in Russia)
Please read history of the region before making such nonsense conclusions.
As to Russia being not much better than America. Russia (as well as Europe, I hope?) seems sick and tired of the political games and "brain-washing" created by the US government, and if America doesn't understand other ways of dealing except those she uses, then, apparently, no one would have other choice than to deal with America using her own methods.
Do CNN, BCC, SkyNews say anything about the fact that before the Georgian assault, the USA and Georgia had been co-operating very closely in the military field? A month before the attack they had a joint military training. A lot of military machines Georgia used for ossetinian genocide were given to Georgia by the USA a while ago. What right did Saakashvili have to place a EU flag behind him during the interviews to western mass media?
Do those mass media show any interviews with osetinian refugees and inhabitants who were in the very hot spot? Have they presented any cultural and political story of the region? Have they mentioned that there were dark-skinned American mercenaries attacking ossetinians?
Has the United Nations Security Council made any decision on the problem? The latter, having been summoned for 4 times so far, revealed itself incapable. They just can't accept that the US ally, Georgia, was engaged in genocide. (Georgia stupid actions played a biiiiiiiiig dirty trick on them.)
The US and EU have simply reached a deadlock at how to save their faces. They got into a snare they have been settling themselves.
