Sue, you have it almost completely backwards. The government in Ukraine was not pro-western. It was led by pro-Russian stooge Viktor Yanukovych. Most of the country was pro-western, but he took the Russian money and declined to sign a trade agreement with the European Union. It wasn't just the carrot of the money but also the stick of the crippling financial retaliation that Putin threatened if the deal was signed, as well as Yanukovych's pro-Russian sentiments. The outrage among the population at this move is what led to Yanukovych's overthrow and the subsequent Russian actions against Ukraine and its new pro-western government, including the invasion of Crimea and the eastern parts of the country. Obama's involvement consisted of imposing sanctions on the Russians in response. It's a bit of a stretch to call that starting a civil war. As for the stuff about mineral rights and hoped-for profits for the "coup-masters," that comes straight out of the Russian troll factory handbook. A lot of what is spread online originates in places that many who consume it don't realize.

Go back one year and there are a number of articles about Yanukovych being pro western - He only became pro Russian when he turned down the ridiculous offer made by the IMF and supported by the EU and US. They were offering 5 billion and he had to virtually sign away Ukraine mineral rights. The Russian's offered the Ukraine the 17 billion they owed and a discount on gas. This initiated the US funding Western groups (who it turns out celebrate Hitler collaborator as a hero). The retaliation was the removal of favored pricing.
As far as any invasion by Russia. You do know that it is a major Russian naval base and guess what - they had 20,000 military there as a normal cadre. The only people that supported the overthrow of Yanukovych were the Western regions. The Eastern regions saw it as a coup and yes it is a civil war. The Russian's support the eastern faction and the United states supports the western faction. BTW did you ever read articles in 2012 and 2013 about what the IMF was asking for as collateral? You may be falling prey to the Western propaganda factories.

I do have one advantage and it is why I have had an interest in the Ukraine - A friend of mine sent me some video via FTP of the protests with a note - listen to them --- they were speaking Esperanto. That is generally used by former Soviet Union countries much like the west uses English when speaking to people of another country. Those protestors weren't all Ukraine. A lot of the violent ones were imported. Who paid for those added protestors? It was a coup.
