Yes, they kinda left, but then they .... attacked Russia trying to get other parts of Russia to "leave". And their "kinda left" was no more.
What you are missing is that it was in response to Russian attacks.
Oh, I see you did read on the topic but still lie. No there were no russian attacks, there was the usual attack of "separatist" on georgian forces and Georgian forces on separatists. EU tried to blame Russia very hard and the best they could do was that.
Crimea: Russian troops were legally there, all they did was politely ask Ukrainian troops to leave and don't interfere with the referendum. And it's not like it happened in the vacuum. Government in Kiev was just overthrown in the violent coup and country was in chaos with all kind of armed people running around.
Ukraine threw out a Russian puppet, Russia reacted to their plans being thwarted with a fake rebellion.
Complete and utter bullshit. It was a coup supported by ukrainian nationalists and western governments in which they failed to take control of wast chunks of the country. and it is no wonder when these idiots openly suggest hanging their opponents. Imagine if Trump suggested hanging mexican-americans?
Even if true it has nothing to do with those fake rebels.
This is true, there were no rebels in Crimea, there was simply no need. It was so pro-russian that even Ukrainian nazis knew there is no point in going there and starting a mess. There was literally just a couple of cases of drunk maidan idiots trying to get to Crimea after the coup in Kiev, they were immediately beaten and sent back, long before the idea of taking back Crimea.
Everybody including you knows that. That's why you don't ever talk about conducting another (fair) referendum in Crimea.
Moscow loves fake rebels, when a rebellion asks for help from Moscow you can assume they really were acting at Moscow's behest all along. Especially in this case where that "rebel" leader was discovered to be a Russian general.
Bullshit, rebels in Eastern Ukraine are real. As real as as the ones who overthrew Yaniukovich.
