It might not have been orchestrated but it was heavily funded by the US. I seem to remember watching a video where a Ukrainian girl tries to emotionally explain why people should support Maidan. The video had almost 10 million views. I did some researching and it turns out the video was funded by a US senator. Then there's Pierre Omidyar funding opposition groups through USAID and who knows what kind of other funding Maidan has received.
I don't think it's a conspiracy that US successfully managed to get Ukraine out of Russia's hands. A good thing, some might say.
