I suppose it was awkwardly phrased on my part, which invited that comment. Russia's act of aggression is an act of war against Ukraine, but Russia calls it special operation, while US is engaged in various conflicts, which it deems 'anti-terrorism' activity. This is what intended to mean by that sentence.
What is more interesting is that US is now officially in a proxy war with Russia as well.
Ukraine is a proxy war and has been since it broke out in 2014 - plenty of evidence to suggest the US was nation building there too under the Obama admin (Nuland Pyatt tapes). Biden and Kerry were all over Ukraine as senators / VP since shortly after the fall of the USSR, and don't forget Ukraine had an IMF loan up for renewal (which was predatory to say the least) in 2013 right before Euromaidan, and Russia was going to bankroll their loan instead. Wouldn't be the first time a coup follows an IMF loan.
Don't take it from me though...
