You’re both wrong. It’ll be more of an evisceration than evaporation.

There are several countries who gave up WMDs, either deployed or in development. Iraq, Libya, South Africa, and Ukraine. Of these, only South Africa was left alone. And to be clear, two of the remaining three were attacked by the US.

So what we’ve done here is signal to the smaller powers that they should never negotiate away their WMDs. You’re just going to get invaded, anyway. I can’t blame smaller powers for going that way at all.

Edit: and to be extra clear, this also applies to Iran and N Korea. They have no incentive to give up their nuclear programs.
