Let's recall that Russian false flag operations are already a well-established fact in the Russo-Ukrainian War.
On July 16th, 2014 the Russian Army's 53rd Anti-Aircraft Missile Brigade snuck across the Ukrainian border under the cover of night while Putin was promising the world that there were no Russian troops on Ukrainian soil. Satellite intelligence confirms that the Russians shot down Malaysia Airlines Flight 17 with 298 civilian passengers and the Russian Col. General reported back to the Kremlin that a Ukrainian Jet Fighter had been shot down. Obviously, this was a false flag operation with Russians masquerading as Donbas rebels in the hopes of escalating Ukrainians attacks on those rebels as pre-text to Russian invasion. The Russian then snuck back across the border the next night with one BUK surface-to-air missile launcher missing one missile. The Russian Government first reported the event as a rebel victory over the Ukrainian Air Force, then once they discovered they shot down civilians, changed the story to say that the Ukrainian Air Force shot down the plane. When intelligence revealed that the plane was brought down by an S2A missile, Putin changed the story again to blame rebels in the Donbas region. This ended up being the busiest three day period ever for the Russian disinformation troll farm, The Internet Research Agency, tweeting out more 111,000 fake news tweets in 72 hrs
That Putin is running false flag operations during the Russian invasion of Ukraine is a fact established in International Court and already punished with important sanctions on Putin from the EU, The Nederlands, and Australia.
