President Trump's alarming warning to North Korea on Tuesday stunned many Americans, with Sen. John McCain observing that "the great leaders I've seen don't threaten unless they're ready to act and I'm not sure President Trump is ready to act." While it isn't clear how pre-planned Trump's threat was — that North Korea would draw "fire and fury like the world has never seen" if it continued to intimidate the U.S. — the president's words were nevertheless a clear and chilling echo of former President Harry S. Truman's speech after dropping a nuclear bomb on Hiroshima in 1945, The New York Times reports:

Seventy-two years ago almost to the day, Truman told the Japanese that "if they do not now accept our terms they may expect a rain of ruin from the air, the like of which has never been seen on this Earth."

At the commemoration of the second bomb drop three days later, on Nagasaki, Mayor Tomihisa Taue warned Wednesday that "the nuclear threat will not end as long as nations continue to claim that nuclear weapons are essential for their national security," USA Today reports. Jeva Lange
