Just the fact that the USA can credibly threaten to use nukes means it’s completely rational and normal for everyone else to want nukes of their own. Liberals say Kim Jong-Un is insane specifically because he uses this justification for why the DPRK’s possession and testing of nukes is legitimate, and the western press insists the premise is flawed: That the USA would never ever consider using nukes.
That’s stupid. They literally already have. And that’s why this threat feels credible too. If the threat is credible (and that’s up to your own interpretation here), then the basis for calling Kim Jong-Un insane is invalid.
Do you lecture people about how your country is a democracy and whatever enemy country is a dictatorship?
