What I'm arguing for? Logical consistency. Moral consistency. If the reason to sanction DPRK is that they acquired nuclear weapons without the consent of the current nuclear powers, then all states which do the same should be sanctioned. If the reason to sanction DPRK is because they might wreak havoc with massive weapons, then countries that are already wreaking havoc with massive weapons should be sanctioned. Your argument is that Israel and the US should not suffer the consequences of sanctions because they aren't sanctioned. My argument is that there is not logical or moral consistency in sanctions.

And no, I don't accept that this is an argument for nuclear weapon proliferation. Those countries that developed nuclear weapons pulled the gate shut behind them, forbidding any other countries from getting them. We can see the hypocrisy in that. But then when a US ally like Israel, or a strategic partner like Pakistan acquires nuclear weapons it is ignored. Only DPRK or Iran could possibly be dangerous because... well because they aren't cooperating with the US.
