I agree with you pretty much but the previous court ruling basically said Trump had to use the real military to protect federal assets not state national guards

So if states can make any deal at all that lets Trump use the national guard but not completely then maybe Trump will stick to it or at least not send in the real military (or try again to usurp control of the guard)

Edit to clarify: usurping the national guard is using the insurrection act, sending in the military would be trying to protect federal assets with or without the insurrection act (untested)
