Ukraine? nah, not unless they invade. I'd say inflation, government overspending, Too much quantitative easing over the years, failure to react to the realities of covid which we haven't seen the worst part yet. Lack of an energy policy to keep us self sufficient, Government incentives caused people to leave the service industry and other parts of the workforce, lack of faith in Leftist government, leftist government policy. Open borders and city crime waves again due to Leftists all cause the population to become unstable because people can't plan what catastrophe will hit us next. Trump can fix it if the House GOP can stave off the collapse.
What's that supposed to mean? The disease is nothing compared to the hyper-ignorant reaction to it. Are you expecting the disease to be worse or the authoritarian government reaction to be worse?
