Incorrect. This war started in 2014 when Putin induced Yanukovych to betray the Ukrainian people by reneging on the EU economic agreement and seeking to tie Ukraine to Russia via the Eurasian Economic Union. This, not the CIA, is what set off the protests that lead to Yanukovych fleeing to Russia. And this is the little inconvenient fact that Russian apologists always gloss over.
Trump says the State Department helped overthrow the Ukraine in 2014. I believe Trump, not you.
