John Bolton has left the White House and those of us who desire some modicum of peace in this world can breathe a sigh of relief. Bolton was appointed to serve as Donald Trump’s third national security adviser barely a year and a half ago, succeeding H.R. McMaster. It was always a strange choice: Trump’s foreign policy is premised largely on hard-nosed (and often hard-of-luck) deal brokering, while Bolton’s preferred method is to bomb other countries.
