Roger that Roger,I don't want to sound like the 2nd coming of Neville Chamberlain, bullys need to be confronted, but the way the stars are aligned right now,(pandemic,inflation,total political clusterfk,this is not a time to start shooting in Europe, Biden is playing it pretty right,he's giving the Ukranians weaponry to hinder the Russians, and also beefing up the surrounding NATO countries with additional forces, if those countries are FKD with Artical 5 means we are committed to action vs Russia. NO fighting in Ukraine on our part let Vlad pay a price and see how much internal dissent unfolds once the casualties mount all while beefing up the surrounding area. Don't underestimate Russias weaponry as you previously mentioned however, The Russian S-400 Air defence system is said to be the most lethal in the world at this time, supposedly superior to any Western system according to many military experts. The days of people being in awe of our tech(eg the laser guided weapons that shocked the world in the gulf wars are now possessed by everybody (China,Russia, even the Turks and Iranians have capable strike drones eg the Saudi Refinery attack shocked the West. So while I believe we still have the upperhand in tech it has shrunk considerably the last 15yrs.
