Ukraine got rid of it's nuclear arsenal after the breakup of the Soviet Union. They did so only after being assured that Russia, US and UK would guarantee their security in the Budapest Memorandum.
After Trump's monumental fuck-up this weekend, no country will ever agree to relinquish their weapons again, nuclear or otherwise.
The security that we relied on and the world as we know it has changed, almost overnight and Nato is already dead in the water.
It would be comforting to think that Trump, Musk and Vance are an aberation, that could be overthrown, yet they received backing and approval from a supine Republican party and a voting stupidity majority of US citizens. Dark times indeed.
