Trump just destroyed US advanced arms export. He is efficient at tearing things down, gotta give him that.
I think everyone is underestimating the changes that are happening. Obviously if Trump wanted a prosperous USA, he wouldn't be isolating it, and destroying the federal government and wrecking scientific research and diplomacy across the world.
but an overall poorer US with a permanent far right government under the control of a small group of rich lunatics is better for those rich lunatics.
Really sorry for Ukraine, though. We knew back in November that this meant certain death for them.
