You realize Muammar Gaddafi only died 12 years ago and Russia only invaded Ukraine two years ago? Nuclear weapon programs take at least that long to develop. Ukraine and Libya had programs (Ukraine actually had weapons) and abandoned them, much to their demise. If they kept their programs, they wouldn't have had these problems.
The key word in my comment is "will." That's a prediction. You can ping me in 25 years to see if this works out. In the mean time, people are taking this prediction seriously (it isn't only my prediction) when discussing global politics.
