Do you deny then that the CIA collapsed the communist regime in Afghanistan, or Iran's Mohammad Mossadegh, or Jacobo Arbenz, or armed Contras, or the tried to overthrow the Sandinistas or the Castros, and half a dozen other things? They don't.
Those operations were conducted by perfectly human and downright boring means. They dont just wave a magical wand and conjure a revolution out of nowhere.
The actual process of creating an army in a foreign country from scratch is done by the Green Berets and it would take a long time if you wanted a big force. It's also done through conventional military channels and the constitution requires congressional approval for long term military deployments which means you can't hide a massive operation of that type. So the US doesn't just conjure up militaries of foreigners, that would be wildly impractical. Small foreign units are sometimes are useful (that's why the Green Berets exist) but what's much, much more common is that the existing military leadership can be won over.
Unless I misread something, he isn't saying anything like "The CIA created the Ukrainian Army and is running all operations in the country", he's saying the CIA has had a hand things such as the Orange Revolution and the Maidan, which hardly requires anything that isn't relatively "boring". It seems to be incredibly naive to think that the CIA had no involvement at all in either event and simply sat back and watched as allies of the EU (and, by extension, the US) took over a strategically important country completely on their own.
Further, while there are plenty of Russians fighting for the separatists, it seems just as silly to act as though the DPR/LPR are literally just fronts for the Russian Army, like the people living in those regions were loyal flag waving Ukrainians happy with the current state of the country and were unfortunately taken hostage by foreign invaders. It also seems silly to suggest that Putin himself orchestrated the rebellion, as if he would create a warzone on his own border so he could constantly have to navigate between Russian public opinion and Western international outrage, all for the
possibility of gaining a fairly small amount of land that would likely be a devastated mess.
