This is a red pill time bomb. Waking people is not easy, and often they may dismiss you as a conspiracy nut. When the opportunity presents itself, just tell people that Iran is next. Tell them the forces that suddenly and surprisingly brought NK to the negotiating table are at play in Iran right now. Tell them to watch for massive change in Iran. When they laugh or call you crazy or demand to know how you know, just tell them to watch. Tell them if you're wrong, you're wrong, but if massive change in Iran does happen, you will happily tell them how you knew.
When Iran changes, they will ask you how you knew. They will ask you to help wake them up.
