Listen in on Morning Joe as senior contributor Mike Barnicle and The Washington Post foreign affairs columnist David Ignatius discuss President Donald Trump’s threat to unleash “fire and fury” against North Korea. “In talking to people in Washington…I was struck by their fear that this is less-than-rational behavior coming out of the Oval Office — not the White House — but the Oval Office. Their fear is that the accidental start of a war could easily occur,” says Barnicle, who recommends the President read – or at least listen to – John Hersey’s classic “Hiroshima,” which tells what happened on August 6, 1945, when Hiroshima was destroyed by the first atom bomb ever dropped on a city, told through the memories of survivors.
