Mike Pompeo, former US secretary of state, wrote in a book published on Wednesday that India and Pakistan had come close to nuclear war in 2019 and that US intervention prevented escalation.

“I do not think the world properly knows just how close the India-Pakistan rivalry came to spilling over into a nuclear conflagration in February 2019,” the likely future presidential contender wrote in “Never Give an Inch,” his memoir of his time as Donald Trump’s top diplomat and earlier CIA chief.
