When Harry S. Truman became president in April 1945, military advisors briefed him on the coming advent of the atomic bomb.
“Nobody ever goes to Truman and says, ‘should we do this?’ They go to him and they say, ‘we are doing this,'” Alex Wellerstein, an author and nuclear history expert, said in a new episode of Radiolab released Friday, titled “Nukes“.
But Truman quickly learned they were cities packed with women and children — and asked his generals to halt a third atomic strike in the works.
“He has immediately written back to them, and says, ‘Just stop, knock it off. You are not going to drop another bomb without expressed permission of the president of the United Sates,'” Wellerstein said.
The Radiolab episode explores the question of who or what — if anyone or anything — can stop a US president today from launching a nuclear weapon. And their answer is not comforting.
“The system is set up so that only the president has the authority to order a nuclear war. Nobody has the right to countermand that decision,” William J. Perry, the 19th Secretary of State who served under former President Bill Clinton, from 1994 to 1997, told Radiolab.
“He might choose to call the Secretary of Defence or the Secretary of State, or the Chairman of the Joint Chiefs of Staff, to get his advisors’ counsel,” Perry added. “But even if he does that, he may or may not accept that counsel.”
Permission to nuke not required
The single-handed authority of the US president to use his “nuclear football” has been public knowledge for decades.
Yet given President Donald Trump’s recent and alarming nuclear rhetoric, a $US1 trillion program to modernise US nukes, and Trump’s April 6 retaliatory strike against Bashar Assad’s regime in Syria — a close ally with Russia, which is a nuclear superpower — it’s a concept that remains as timely as ever to re-explore.
At stake is a global nuclear exchange that could annihilate hundreds of millions of lives and sour Earth’s atmosphere, water, and ground for generations.
Robert Krulwich, one of Radiolab’s hosts, asked Perry further about the checks and balances of the president’ first-strike capability. Their conversation was revealing:
Krulwich: “If you as Secretary of Defence say to the president — he says, ‘let’s go,’ and you say, ‘let’s not,’ can you…”
Perry: “First of all, if he calls me, and then if I say, ‘Mr. President, that would be a very serious mistake, don’t do that,’ he might or might not accept my advice.”
Krulwich: “Are you necessary to launch?”
Krulwich: “Suppose everybody in the room thought it was a bad idea. Would he still be able to do it?”
Perry: “Yes. He has the call directly to the Strategic Air Command to do the launching, and they will respond to his orders. They don’t call the Secretary of Defence or the Chairman [of the Joint Chiefs of Staff] and say, ‘should I do this?’ They do it.”
You can listen to Radiolab’s full 56-minute episode below:
The audio highlights legislation introduced by Rep. Ted W. Lieu and Sen. Edward J. Markey (both Democrats) to curb the president’s nuclear-strike powers. The legislation, which came about before Trump became president, would forbid the use of nukes until Congress officially declared war on an adversary.
But the episode mainly focuses on the story of Maj. Harold L. Hering.
Hering aged out of flying helicopters during the Vietnam War and decided to take a job as a missilier: one of many pairs of people in bunkers across the US that can launch intercontinental ballistic missiles tipped with nuclear warheads.
During his missilier training, Hering asked who or what is checking or balancing the president, who may be mentally or morally unfit to make the call — and the rest of the tale is fascinating if not alarming history.
