So why is Iran being persecuted under the non proliferation treaty while Israel is not?
(Hmm, hmm? Tell me that you bastards who support Israel and demonise Iran, bastards!)
As is pointed out in the comments, because Iran has signed the NPT and Israel has not. There is thus no legal justification for doing anything at all about whether Israel has nuclear weapons or not.
We do want to uphold international law, after all, don\’t we?
