Neocons McCain and Nuland actively took part in the protests in Kiev, and promised the dissidents money from the US and EU that they would/could never deliver.
Broken EU promises of bailouts is why Yanukovich sided with Russia "suddenly and mysteriously": there were 15 billion good reasons to do so. Putin is a thug and a maddog killer but he doesn't play the con-games that the EU and US do.
The US fomented that coup thinking that Russia would roll over, or at most start a huge skirmish and kill a few hundred thousand people that we don't give a rat's behind about. Then we would be able to sell ICBMs and ABMS on credit to people (aka "muppets") that can't afford toilet paper, and Russia would be a step closer to rolling over and accepting ECB/IMF's terms of surrender. It didn't work that way.
Now, Ukraine will be the next Greece/Cyprus and the Ukrainian people will get the rubber-stamp bailout package, and hand over all their wealth to the ECB and the IMF.
Either you're trolling, you're that clueless, or next, you'll say the US had nothing to do with Mossadeq and installing a madman dictator over Iran in 1953.
