That's not comparable. Ukraine had weapons it gave up. None of these countries had nuclear weapons. Although, while not being comparable, it's still true that the US's invasion of Iraq definitely hurt nuclear non proliferation, and has remained a driving force in pushing the likes of Iran and North Korea to build up nuclear stockpiles. What Russia's invasion has done is basically extend the desire for nuclear weapons from what are inarguably bad actors on the global stage (Iran, North Korea) to pretty much every country in the world.
