US President Donald Trump could lead the world into a catastrophic war with North Korea because of his inexperience and temperament, former British spy boss Sir John Sawers has warned. The former spymaster warned that Trump’s temperament could plunge the UK into a war in the Far East which would be more dangerous than anything that could emerge in Syria. “[Trump’s] not someone who fills me with confidence,” Sawers told the BBC.

“He doesn’t have the background and the experience and the instincts of being an effective US president, but it is in our interests that we have a US administration that upholds the international system, that supports its allies and supports international norms,” he said. The more serious figures in the US administration have been stepping in to make up for Trumps’ rashness and inexperience after the US missile strike on a Syrian airbase, said Sawers. MORE
