Maybe I will once again regret trying to DISCUSS this matters, BUT as an international lawyer I need to say:
"Fact #1.
There are North and South Ossetia. North Ossetia belongs to Russia. South Ossetia belongs to Georgia. A lot of people living in South Ossetia have Russian passports and are relatives to people in North Ossetia. There are no seperatists there, as western people are being convinced by mass media (watch the movie above)."
Georgia is a sovereign state within its territory and has a sovereign right to rule its area by a central government. If a region within a state creates its own government without any approval of the central government (as a representative of sovereignty), if they declare sovereignty in their region, YES, THEY ARE SEPARATISTS. And if you ask about Kosovo, yes they are separatists in the same way. United Nations still recognize sole right of the state to decide about his territory. That's why Kosovo is matter of disputes and will always be. That's why my country has not yet recognized Kosovo and is not really intending to do it. Not because of politics, but because of law.
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)
"Fact #2.
In Tskhinvali, the capital of South Ossetia, there were Peace keeping Russian forces that had an official credential from the UN to be there and to prevent any military conflicts. On 8.08.2008, by night, Georgian troops fired sleeping inhabitans of Tskhinvali and fired the Russian peace keeper forces, and this led to 2000 deaths of Russian citizens, women, children, peace keepers... (Ah hour before the attack, Mr. Saakashvili declared a start of peaceful talks.)
Would that mean that Georgian troops, practically, attacked the UN?"If Russian soldiers are in this territory as UN soldiers, Russia has no right to enter Georgia to protect them on their own. As they were sent there on behald of United Nations, they have to wait for the command of United Nations to intervene. They can always withdraw the soldiers from the mission to protect them, but not to enter the country - this is UN mission (as you've said), not a Russian one.
Do you think that when Slovak soldiers fighting in UN mission in Afghanistan were attacked by guerrilas, Slovakia should have sent Slovak army to kill those "bad terrorists"? It wasn't our right to intervene, nor it is now Russian's right.
"Fact #3.
Russia, entering the foreign county, was protecting the Russian citizens and Russian peace keepers. Does so called international law prohibit that? It has nothing to do with separatists (who are actually a tale by western mass media)."
YES, IT DOES. The "so called"

international law prohibits military intervention in area of another state without approval of UN (and YES, all the cases of such intervention in the past without such approval were violating international law). There were few Slovak citizens in Georgia. Should we send there Slovak army to protect them? No, we have no right. Our embassy is trying hard to bring them home, but we have no right to "protect" them by military force there. Russia has no sovereign power in Georgia which means (by a traditional definition) Russia has no right to make any measures of governmental nature (including military actions) in the region of Georgia. You can protect people in your state but not go to another state and fight for their rights there (only on behalf of UN)
"Some history points regarding small european countries in the WWII. Why are they mad at the Soviet Union only? It was a plot created by both the "big" regimes, Hitler and Stalin, if you want to be unbiased. Moreover, Polland itself was taking part in division of Czechoslovakia in 1938. So in the end everyone got what he was going to. But you are misled and misinformed if you blame the Soviet Union only."Me and my Czech colleague were not talking about WWII (when really all countries went absolutely mad) but about the years thereafter. Soviet invasion of Hungary in 1956, Czechoslovakia 1968, Poland 1980, Afghanistan... was not a matter of any other political power than Russia. Should I therefore start any message written to you, Ruslana, by "I still remember 20 years of watching Russian soldiers in my country"?
"...and yes, we should remember every invasion of the past whenever it was and whoever started it."As you've said. But I don't see a point why to blame present German government for Hitler or French government for Napoleon. Do you see a reason why? Just to remind you that all these guys on their way to Russia went through our
"small european countries".
"I personally think that "international law" is another tale. If politicians want to do something, they do it, neclecting any law." Saying this machiavellist idea, you are in no way better than USA, which has been criticized (by myself as well) here just for this attitude. Is Russia really the same?
Please stop mixing law with emotions (though I understand and accept all emotions involved here). Don't use law as a support for any military involvement, since you will surely fail to evidence it. If you want to write about emotions, write about them but don't expect me to react to them. If you want to discuss law, I am prepared to take part.
I personally doubt that anyone will read such a long article here. I am sorry
