And we didn't attack them because .... ?
N.Korea Says It Has Nuclear Arms, Spurns Talks: "Secretary of State Condoleezza Rice played down the dramatic announcement, saying the United States had assumed since the mid-1990s that North Korea could make nuclear weapons."
And so we attacked Iraq, whom we suspected on some fabricated evidence. We bombed an aspirin factory in Libya for a similar reason. We are suspected of wanting to attack Iran for much the same thing. North Korea, of course, we let go despite the hardest proof we had since we documented pre-WWII Germany's heavy water experiments.
Someone, please, take a few moments and explain this to me.
