Is it time to leave?

Everyone in the US is so calm with this Iran/US shit. Im clueless when it comes to politics and warfare. Why arent people trying to leave? I feel like the world is about to nuke the shit out of us at some point. And being in a uncivilized uncontrolled place like america probably isnt the best place to be in the apocalyptic stages of war. Someone said im being dramatic but am I?
