My parents and I left our home in the Gulf on Friday evening to visit family in Switzerland for my birthday last week. We were supposed to return today, but the airspace there is now closed. Do you think things will go back to business as usual soon?
No, there is very little for Iran to gain by trying to make the conflict bigger, they do not have the resources for any troop movements abroad. Some terrorist action on US soil would most likely increase the likelyhood of US boots on the ground, which would not help the regime stay in power. Whereas the proxies in Israel are currently too weak to do anything of value, sure they can probably murder someone of no importance, but not do anything that will help them win or restore peace.
While for the USA/Israel to make it bigger the US congress would need to declare war formally. Currently, there is a thin veneer of plausible deniability that protects Trump, anyone who is not in his propaganda bubble knows this is a declaration of war without really saying it. As all he did was bomb some country with many muslims, which sadly is just modus operandi for the US presidents
