Stan,

If the military is required to protect the homeland by operating in the homeland it can do so (if they're directed to by the appropriate authorities), but the current threat sure as heck doesn't require that and it is unlikely that this particular group will ever require augmenting the police with the military again in the near term with the possible of exception of deploying troops to airports in reaction (not to prevent) a successful attack. I think the local police and feds can handle most of the issues. For the ones they can't they can always ask for help.
