There was a coup that overthrew the government in Kiev. One where nationalists had a big role in. That directly threatened the Crimeans with their views and political positions. Afterwards they formed self-defence forces, which were also supported by local police.
Only after that did Russian Forces move in to support them. The first several days they were on their own and there were several instances of thugs from Kiev trying to enter Simferopol and Sevastopol and being beaten up and sent back home.
So the sequence of events which I am trying to point out to you is: Coup in Kiev - threats towards Crimeans by nationalist thugs that just illegaly took power in Kiev - formation of self defence forces in Kiev - Russian Forces enter Crimea.
The Russian trolls and apologists are trying to rewrite history again. There was no "coup" in Kiev; the government was the same elected government that existed under Yanukovych. And Yanukovych himself wasn't "overthrown"; he was cast adrift by his own allies. The Western officials were just as surprised by the meltdown as anyone else.
You should remember that it was Yanukovych first agreed to sign a trade deal with the European Union but then, under heavy pressure from Moscow, abruptly turned away from that long-planned pact. When his own citizens went to Maidan Square protest that about-face, he answered their concerns with gunfire. It was then that his own party
- and his own supporters in Parliament - abandoned him. Parliament remained intact; the government didn't change. Ukraine continued to have a legal government. Only the President - having been exposed as a puppet of Putin - ran away with his tail between his legs. In the disarray - and seeing his crony exiled from Ukraine - Putin seized an opportunity to forcibly steal Crimea.
I realize that you will never see the truth on Russian State "News", so you will continue to perpetuate this drivel... that is only for propaganda, to assure the masses that all is right and good in Mother Russia. I also realize that many Russian cronies - and you may be among them - dream of a return to the days when Russia was the great power of the Soviet Union. You may wish all those territories who chose self-government would return to such a state... but they won't. You may send "little green men" to seize portions of other sovereign countries, but the rest of the world will react - as it has - with disdain.
Continuing to spread distortions - and outright lies - may earn the Russian trolls a few rubles in St. Petersburg, but as those rubles become more and more worthless, even the paid propagandists may be searching for other answers.
Now in hindsight it is pretty easy to see that this was absolutely the correct decision for Russian Forces to move into Crimea and support the Crimean self-defence forces. Had this not have happened, we would have had a mess much greater than in Donetsk.
Donetsk would not be such a "mess" if the Russian invaders and agitators would simply go home.
