I would like to add that Ukraine never possessed nuclear weapons!
A portion of the USSR's nuclear arsenal was stationed here, and after Ukraine's exit from the Union, it became non-functional—like half a car or a computer without a motherboard. It might exist, but it's of little use.
If you carefully read the text of the Budapest Memorandum, aside from the title itself, no guarantees for Ukraine are mentioned.
The only thing stated there is that in the event of aggression against Ukraine, the parties must immediately convene and discuss a plan for further actions—and that's it!
I completely agree that nowadays, it's unwise to trust anyone!
Additionally, soon we will all witness a fair, multipolar world order based on the interests of several strong players, not just the United States alone. I think it will be awesome!
