Trump/Brexit - 'We may be sleepwalking towards world war, says respected Princeton historian'

We may be sleepwalking towards world war, says respected Princeton historian: 
Prof James said that countries had become locked in an information arms race similar to one that began in the years preceding World War One.
"I think [a world war] is absolutely a serious threat," he said.
"In that sense I think the aftermath of 1907 is as interesting as the 1930s.
"Because after 1907 the foreign ministries, defence ministries, intelligence agencies started to operationalise information - to think that information was essential to the control of military events - and there was a kind of arms race in terms of communications control.
"And we're seeing that kind of arms race at the moment I think."
