So do you think Russia annexing Crimea in 2014 happened in a vacuum, or do you think it was a response to the Ukrainian coup which Russia claims was partially financed and fomented by the CIA in order to install a pro-NATO puppet regime on Russia's border?
Following your own logic, that coup did not happen in a vacuum either. The coup was against a pro-Russian puppet regime that did not hesitate to shoot and kill their own civilians. Any western influence agens involved probably did not have to work very hard.
