They Ukraine were part of USSR like Kuwait was part of Iraq. South Korea was part of North Korea, South Vietnam was part of North Vietnam. If the Ukrainians join NATO or Russia, they will lose their sovereignty. Maybe they should take a vote and have majority make the decision on what country that want to be absorbed by, Russia or Europe or none.
Who knows the real reasons Russia or Europe want to absorb them? Taxes? Natural resources? Somebody wants something. Special interests at work? I like sovereignty for all countries, especially the USA.
There was a populist movement starting in many countries. Like a global commune the providers don’t want to support the slackers on a free ride. Will the trend continue? Look at Brexit? Only the start? Looking out for the next 100 years? Back to pre 1900s? What country wants to be married to a country with baggage?? LOL.
