I agree about the current Ukrainian government, and my sympathies were far more for Ukraine prior to the U.S. deposing its elected president and installing a puppet. I am also for peaceful secession movements. But it takes two to make peace, and if the central government decides they're not allowing secession, then there will be war. And my sympathies are 100% with Ukraine when it comes to them vs. Stalin or any other USSR leader. I didn't believe all the bullshit coming out of the Western media about Ukraine being full of neo-Nazis and white supremacists (which was their tack before they about-faced and decided Ukraine was a bastion of liberal democracy when Russia invaded). Ukrainians don't help themselves by waving swastikas and adopting SS symbols, but they're not Nazis. There are two sides to every story, and as an American I really resent (1) America being involved on either side, it's not our fight, and (2) the American media distorting the facts by presenting only one side at a time -- are the Ukrainians evil Nazis, or heroic democratic freedom fighters? Because they can't be both at the same time. And NATO was flat-out wrong to push itself right up to Russia's borders, wrong to turn itself into an offensive alliance rather than a defensive one, and wrong to even exist after the Warsaw Pact broke up. My beef is not so much with Ukraine, it's with America's involvement in it and the American media's blatant manipulation of the public to get it to go along with whatever our government wants.
America got involved in WW I for similar reasons (financially backing only one side in a war), then that war led to WW II. How did the rest of the world getting involved in Serbia's conflict with the Austro-Hungarian Empire work out for Serbia? How has it worked out in the long run? Serbia got taken over by Austria-Hungary, then the Nazis, then the Communists, and finally bombed into submission by their "allies," the Americans and British.
I support secession in my own country; why wouldn't support it elsewhere? It's better to get along as friends than stay together as enemies.
