Oil prices will get a lot more interesting, if we allow Iran to build nuclear weapons and help countries like Syria and Sudan to do the same.
It's really just an excuse to for the speculators to bid the price up and make Billions per week. Iran has had Surface to Surface anti-shipping missiles lining the Straights of Hormuz for decades. That's the real threat to oil flow, and they were there when oil traded at $8 a barrel not to long ago.
The Korean kerfluffle is the same deal, hype to increase the fear premium.
The difference is that if Iran could heave a nuclear weapon
into the Saudi/Gulf States/Kuwait oil installations, 100 dollar oil would be a dream scenario.
With that one act the economies of most of the world go into the toilet.
