An interesting development in American politics emerged yesterday in a book by Bob Woodward and Robert Costa of the Washington Post. Woodward, for those who don’t remember, was the journalist who revealed the Watergate break-in which brought about the resignation of Richard Nixon.

According to the book, the Chairman of Joint Chiefs of Staff, General Mark Milley, was so concerned that President Trump was unhinged, that he feared that the President, the Commander in Chief, would authorise a nuclear attack on China.
