WASHINGTON - President Donald Trump has directly weighed in on the White House review of a forthcoming book by his former national security adviser, telling his staff that he views John Bolton as "a traitor," that everything he uttered to the departed aide about national security is classified and that he will seek to block the book's publication, according to two people familiar with the conversations. 

A few weeks ago I wrote that the inclusion of hawks on his foreign policy team meant that US President Donald Trump was more than likely going to antagonise the North Koreans.
