This feels like it assigns too much competence and control to the CIA and not enough to the unnammed "NATO ally" country or countries with the means and motification to make a whole bunch of Russian military infrastructure go kaboom.

This looks like Russian propaganda to me. It's a long-standing Russian claim that the invasion of Ukraine was caused by NATO actions.

Who is this "Jack Murphy"? Search says there are multiple Jack Murphy's, including a clothing retailer, a sportswriter, a murderer, and a right-wing "influencer". I have failed to locate any others, except on this blog, where he says he is an investigative journalist.

So who wrote this?
