The last time that America almost risked a pre-emptive strike on North Korea the gamble offered a spectacular pay-off. Ashton Carter, a leading architect of that plan, recalls that his scheme for bombing the Yongbyon nuclear facility in 1994 assumed that in one or two days the entirety of the regime’s nuclear programme could be levelled and entombed in rubble. Mr Carter, who went on to become defence secretary in the Obama administration, now thinks that an American first strike would only put “a significant dent” in North Korea’s arsenal of nuclear devices and bombmaking sites. “The difference today is that the North Koreans are very good at hiding, burying and moving around their nuclear infrastructure,” says Mr Carter, now at Harvard University.

Ash Carter is a physicist and a defense-policy expert, having served in government periodically for decades. He was secretary of defense from 2015 to 2017. He has spent his academic career at Harvard, where he is today. In this “Q&A,” Jay Nordlinger asks him about some of the biggest issues: nuclear proliferation, North Korea, Iran, the size of the U.S. military. He also asks about the relation between our servicemen and the general American population. Is there too great a gulf between them? Do people sentimentalize our military? Is it okay to say “Thank you for your service”?

Matthew Bunn, Nicholas Burns, Ash Carter, John Park, Gary Samore, and Elizabeth Sherwood-Randall provide expert analysis on nuclear tests and threats from North Korea.

On December 11, 2016, just before my time as secretary of defense ended, I stepped off a C-130 transport plane onto a cold and dusty patch of northern Iraq that had been on my mind for more than a year: an Iraqi military airfield called Qayyarah West. Q-West was a talisman of progress on one of the defining issues of my service, the fight to defeat ISIS. A year before, General Joe Dunford and I had briefed President Obama on a plan to step up the fight against ISIS.
