It was Yanukovich who "shredded" the agreement. And the protesters were backed by the
EU,
not the US. The US didn't do anything to help or harm Ukraine one way or another until recently. In fact, a US official was once caught on tape saying "**** the EU,"
pretty casually. And, furthermore, they were NON-VIOLENT. And they were attacked by a ruthless regime/police state with MILITARY TACTICS. The Oblast of Lviv
LITERALLY SECEDED from Yanukovich's regime over this. LITERALLY.
Wrong, wrong and wrong.
There's so much wrong here I don't know where to start. I guess I'll just say that
RUSSIA INVADED UKRAINE. They literally
HIRED BLACKWATER-CLASS MERCENARIES TO OCCUPY AN AIRPORT. I mean this has LITERALLY been reported EVERYWHERE
REGARDLESS of political lean (with the exception of RT/Sputnik and the Alt-Right). EVERY other major Republican and Democratic and Independent and Libertarian and Right-Wing, Left-Wing, Centrist, Progressive, etc. website has reported on this.
Your clearly building a strawman here to distract from the fact that RUSSIA INVADED AND OCCUPIED CRIMEA. They did EXACTLY what NATO did with Kosovo, only they hired Russian, Ukrainian and other-ethnicity mercenaries to do the dirty work. Either way,
Russian men, weapons and money were involved in the Invasion of Crimea in March 2014.
