Characterizing the situation as having a single source - a "the problem" - is a fallacy of oversimplification. I think the biggest threat Iran poses is the possibility that they'll touch off a nuclear exchange with Israel or use nukes to mine the Straight.
Thanks for the reply. I’m always off the mark so what do I know? I do believe one of the problems is nuclear proliferation, be it in the ME or in the world. The other is the continuing trend to involve the increasingly indebted USA in perpetual wars in the ME.
The ME should take care of their own problems. It’s not our problem anymore. The USA has energy self sufficiency.
