Is it as simple as that? (1) There is a continuum from dirty bombs to full Nukes that makes it a bit more messy. (2) Are Nukes not more "hideable" than this? For example, why has NK not had theirs bombed?
The issue with NK, to my understading, is that any action there would lead to SK ( A densely populated country) being attacked with a lot regular missiles that would be hard to prevent.
Because of a country up north.
