A lose / lose proposition, or a lesser of two evils? Another prolonged war and occupation in Middle East, and waste of good life’s is not appealing. Do nothing and they will eventually be nuclear capable, and rouge enough to actually use. Diplomacy seems to be a long shot at this stage, so unfortunately this seems not to be a When vs If scenario. I also don’t see the world rallying behind this cause, so outside of the staunchest of allies, it would be US going alone.
