Trump got rid of John Bolton but we still have mostly Bolton-approved policies. From Patrick J. Buchanan at buchanan.org:
The sudden and bitter departure of John Bolton from the White House was baked in the cake from the day he arrived there.
For Bolton’s worldview, formed and fixed in a Cold War that ended in 1991, was irreconcilable with the policies Donald Trump promised in his 2016 campaign. Indeed, Trump was elected because he offered a foreign policy that represented a repudiation of what John Bolton had advocated since the end of the Cold War.
Trump wanted to call off Cold War II with Russia, to engage with Vladimir Putin, and to extricate us from the Middle East wars into which Bolton and the neocons did so much to plunge the United States.
Where Trump demanded that NATO nations and allies like South Korea and Japan start paying the cost of their own defense, Bolton is an empire man who relishes the global role and responsibilities of America as the last superpower and custodian of the New World Order.
Trump saw in the hermit kingdom of North Korea an opportunity to end its isolation and bring Kim Jong Un into talks to persuade him to give up his nuclear weapons, in return for a full readmission and welcome into the world that Pyongyang turned its back on after World War II.
In Trump’s passive acceptance of Kim’s resumption of short-range missile tests last August, Bolton surely saw signs of appeasement.
