In an interview with Fox News TV, John Bolton, former US ambassador to the UN, said
BOLTON: Well, I think they’ve basically won the diplomatic struggle. They’ve strung out the Europeans for five years of fruitless negotiations, the net of which is that Iran is now five years closer to nuclear weapons. So there’s very little that’s going to happen.
So I think we’ve played the diplomatic option out. And it’s now Iran, basically unimpeded in its effort to acquire a deliverable nuclear weapons capability.
We’re very close to the point where Iran can use the threat of nuclear weapons to great advantage in the region and around the world, perhaps even delivering such a weapon to nuclear terrorists.
So, the options facing the United States and Israel at this point are really very unattractive and very limited.
Q: So what do we do, if all — you say all the diplomatic options are gone. Do we go to war?
BOLTON: No. I think it’s very unattractive. I do think we have to look at the use of military force. Because the option of Iran with nuclear weapons is even more unattractive.
