Trump himself says that Bolton wants him to go to war with everyone, there are many other people calling for war with Iran as well, you can see quite a few of them in this thread.
It almost happened when Iran downed the drone but Trump made the sensible decision to call it off and this article discusses some of the reasons why Trump was right.

The quickest way to get a war is to sound soft and weak...the way to avoid one and persuade your opponent not to resort to terrorism is to convince that opponent that you’re ready and willing to kick his ass if Hezbollah so much as twitches. The way to win concessions from NK on their nuke program and isolation isn’t to surround one’s self with antiwar activists but to let it be known the hawks are circling and that a deal with the builders of resorts and businesses isn’t just a way to avoid getting one’s ass kicked but is a way to glory and prosperity.
Good cops get nothing from a perp without the presence of apparent ‘bad cops.’
