As an American who lives abroad and travels around the world, I've never had the slightest worry about "oh man what if Iran does something?" But I've had to adjust flight and travel plans several times, I've had cost of living surge, I've witness chaos causing terrorist splinter groups that attack countries around the world because Israel and America have started some stupid conflict and said "we had no choice bro we had to attack them because in 80 years they would've made a bomb that might've killed a civilian bro you have to trust me bro." And frankly, I'm done even taking those arguments in good faith. I simply refuse. The mess these two countries cause has caused far more death than even if Iran had a nuke, ten nukes, or one thousand nukes.
