Biden wants nuclear disarmament of North Korea as a *prerequisete to meet*?
Obama and Biden's administration *screwed Ukraine big time*; nobody can trust USA's word on that for a couple decades
2/ a sovereign state:
Ukraine had decent nuclear arsenal, inherited from Soviet Union
a bit dated & not enough to launch a major war, but plenty enough to keep itself *safe* from foreign attack
3/ a deal made made:
in 1994 Ukraine signed Memorandum, getting assurances of territorial integrity from USA, UK, Russia in exchange for dismantling the weapons (disarmament)
