Or maybe you could ask yourself why most of the rest of the region allows the US to have military bases on their soil, and why they are so concerned about protecting themselves against Iran.

The "whole region" fears Iran more than they hate the US, judged by their behavior.

The people in the region cheer when they see Iranian missiles hit US bases.

It is the Saudis and the other monarchists and oligarchs that have decided to sell out their countries to the US and Israel. They fear their own people more than anything else.

Iran is the only country in the region who has supported the Palestinians. Everyone else has looked the other way. Iran has not invaded any other country. It is Israel that keep the region in a constant state of war.

9/11 happened because US imperialism. The current regime is in power because of US imperialism, as them and the Brits doing the coup in the 50s.
