if they were to try and implement a false flag attack on a civilian center and blame Iran, I think that would probably bolster enlistment rates, but not at any level that would make a discernible difference

9/11 didnt even cause that many people to enlist. Like 40k over a decade or more. Not really impressive in a country of 350 million. And that was at the height of amerikan exceptionalism and jingoism. Nobody cares anymore.
