I probably worry less than most of my friends do about what Donald Trump can or will do to the United States of America and the world in which it resides. He's done a lot of bad things already but most of them seem to me reversible the next time Democrats — or even saner Republicans — are in control.
I'm more worried now than I used to be since Trump has replaced National Security Adviser H.R. McMaster with former U.N. ambassador John Bolton.
Bolton is not your typical Republican operative who believes there isn't a problem on this planet that can't be solved by cutting taxes for the rich. He believes that you need to cut taxes for the rich and go to war against…well, anyone. And everyone. Bolton's the kind of guy who would deal with long lines at the mall by sending in the Marines to carpet-bomb the place.
He doesn't even seem to care much who we go to war against as long as we go to war against someone. Jonathan Chait has more on the guy.
