Few one but a few fanatics want to fight Russia. I know this from years of asking Ukrainians [IN UMAN central ukraine] if they preferred Russian rule or rule of Kiev. The answer was almost always that things were better under Russia. But I admit there were a few exceptions. but in a city of 60,000 people, a couple of exceptions were not significant. But clearly Ukrainians in the USA or other countries are ultra nationalists-- they have nothing to lose.
But besides the few Ukrainian fanatics I can see no point in starting WWIII with Russia which in the already started stages of WWIII will be joined by China, Saudi Arabia, Brazil and to add to that the fact is a vast percent of people in the USA itself hate America and can not wait for a bit of chaos to start rioting, burning, looting and raping --as soon as things get unstable.
