Bolton's exit doesn't signify policy change

The dice were loaded against him, for he was not only opposed to letting up the pressure on the Democratic People's Republic of Korea and against the US president's suggestion of a possible meeting with the Iranian leadership, but also a likely cause of the failure of Washington-Taliban talks.

But that he would be fired for being a foreign policy hawk, a trait for which he was made the US national security adviser, is something very few imagined.

So does John Bolton's departure from the White House suggest a change in US foreign policy?
