A president can’t just “start a war”, muchless order air strikes. dozens of people are involved. Donald Trump yells and hollers all the time and people send Jared to calm him down. There have already been documented instances of this in the Trump admin, and it wasn’t over tweets.
Of course he can. He ordered the assassination of Soleimani in Iraq that could very well have led to a war. Wars are the result of a series of escalations. It doesn't take a lot to knock over the first domino.
