Exactly, that would be the prerequisite. That said, given that these bases have already been demolished, it might not be that big of an ask.

Yeah otherwise it's some serious taking others for stupid behavior on Saudi Arabia's part, making a non-aggression pact without expelling or at least making legal exceptions for foreign bases effectively grants those bases invulnerability. If Mexico hypothetically starting allowing to China to send over loads of troops and build tons of military bases, and then later China attacks the US from those bases, then the US would obviously view that as an act of war on Mexico's part.

So airspaces were used without governments even noticing, genocide land thieves even build a base in Iraq without government knowing or approving, Iran is smarter than that, they can damage world economy by damaging SA & UAE
