This article talks about how the US invasion of Grenada sparked the NK nuclear program.
Which makes perfect sense. If the standard is no country can attack another country then countries don't need nukes. The UN could enforce this standard and Gulf War I was framed in these terms.
On the other hand, if the US can invade whoever it wants for any reason or no reason, then nukes are necessary for any country that values its sovereignty and might ever be at odds with the US.
The voracious US appetite for war drives nuclear proliferation. The lessons of the axis of evil speech: being an enemy of the US gets your govt overthrown but having nuclear weapons will save you.
I was too young to remember the Vietnam War, so Grenada was the first war I experienced. That was an unusual and long period of peace but it was all I had known so my expectation was set, just like your expectation of normal gas prices is set by what they were when you started driving. Grenada was shocking, there was no build up. I found out by reading an afternoon newspaper. I was with a friend and I said "This is clearly a war, congress didn't declare war, only congress has that power (school had recently covered the constitution), so I guess they'll have to impeach now! amazing." my friend: "what? who cares. you're weird." His grasp of politics was much better than mine.
The article shows how Grenada impressed NK too. It was the first domino.
