Trump is such a moron, many countries have pledged continued support to Ukraine, and USA is less relevant to the war now than they ever were. USA is not even the main weapons supplier anymore, even with purchases of American weapons to Ukraine by NATO allies.
Trump has very little weight in these matters by his own design.

I am so happy that just this week, I found great alternatives to 2 American products an amplifier and new PSU for my computer. I would have bought if it wasn’t because I have a near total boycott of American products and services. The only exception is if there 100% isn’t any useful non US alternative, and it’s something that is important to my quality of life.
