All of Islam will unite in hatred against US/Israel aggression. Then Russia & China will step in to back Iran so it becomes WW3 (Europe will get involved too of course & so will Australia)
We civilians stand to suffer the most with sky rocketing inflation & fuel prices to soar. Global supply measures will be tested & under pressure. Widespread famine & death from war escalation to come. This time WW3 going to be much much worse than WW2. No where is safe.
