You have to remember that's it's not like it is in films, where they have a big red button on their desk. For him to resort to military action, he has to go through loads of protocol and the action has to be approved by far more reasonable people. He can't just lose his temper one day and start launching missiles, it just doesn't work like that... especially now that his power has been diminished.
He probably couldn't take military action now even if he wanted to. You really have nothing to worry about in that regard, it won't (and probably can't) happen.
