The US is just taking it as a given that it has de facto jurisdiction over the nations of Syria, Iraq, and Iran, and that any attempt to interfere in its authority in the region is an unprovoked attack which must be defended against. This is completely backwards and illegitimate. Only through the most perversely warped American supremacist reality tunnels can it look valid to dictate the affairs of sovereign nations on the other side of the planet and respond with violence if anyone in those nations tries to eject them.
