Daniel Ellsberg, the former United States military analyst who leaked the Pentagon Papers to the New York Times and other newspapers in 1971, on Sunday implored U.S. officials to disclose any information that could avert a war with North Korea.

“I would encourage people who now know that we are being encouraged to go to war with North Korea on false pretenses basically on what the prospects really will be, and what the consequences will be,” Ellsberg told The Cats Roundtable on New York’s AM 970 radio station.
