I really didn’t think Iran’s response would be to immediately start lobbing bombs at all their nearby buddies.
At least activate all your sleeper cell terrorists in Europe or something cmon do something interesting.
They don't have "buddies". Every surrounding state is a sunni majority, or sunni controlled country. It's also ethnic, as the Persians don't like Arabs, and Arabs don't like Persians.
Their immediate neighbor Iraq fought a trench war with them, complete with chemical weapons, for 8 years during the 80s. The Iranians are the largest sponsors of Palestinian groups and splinter minorities in Arab states across the entire Middle East. No one likes them in their current form. They'll have more than enough targets to fight before some poles start feeling the heat, if ever and it'll likely be token and disorganized.
I'm pretty sure most terrorists groups are sunni.
Maybe in ideology, but certainly not in funding. The era of self made Arab billionaire donations is largely over, and "Islamic charities" are too small/disorganized to cover the kind of training/weapons a state can pour on random peeps to make rebels.
Iran is the leader, then the arabs(secretly), then Pakistan.
It's mostly to fuck over their ideological neighbors.
Hamas, Hezbollah, the houthis, Syrian Insurgents, Iraqi insurrectionists, Afghans who are not taliban(shia), etc.
They are immediately concerned with their neighbors and Israel.
If Iran completely crumbles it will likely destroy hamas and hezbollah's ability to do much in Palestine.
