Just a comment, while the west's lack of support here angers me to no end (Russia I don't blame because how could you trust Russia, especially at that moment when so much was changing) while Ukraine had nukes physically, the actual control capabilities were all in Russia and it would have cost Ukraine a lot (money they didn't have at the time) to convert/maintain them to something usable anyways. Not that this is an excuse, but the situation isn't as clear cut as 'they had nukes and could have used them for their own defense if only the west hadn't taken them away'
