Behind the Bastards

Part Three: The Men Who Might Have Killed Us All

December 9, 2025

Key Takeaways Copied to clipboard!

  • The necessity of the atomic bombings of Japan remains highly debated, with evidence suggesting Japan was already defeated and surrender was sought to avoid Soviet involvement and partition, rather than solely due to the nuclear weapons. 
  • Key military figures like General Curtis LeMay immediately pivoted from using the atomic bomb against Japan to aggressively promoting nuclear weapons as the sole future of the military, often lying about the horrific effects of radiation poisoning to gain public and political support. 
  • The post-World War II military establishment, driven by figures like LeMay, prioritized the development of the Strategic Air Command (SAC) and nuclear deterrence, leading to a period where the US possessed hundreds of nuclear weapons while the USSR had very few, creating a dangerous window for preemptive nuclear war. 
  • General Douglas MacArthur was deemed dangerously unhinged for proposing extreme measures like irradiating the Korean border with cobalt to block Chinese reinforcements, leading to his removal by President Truman. 
  • The development of the thermonuclear bomb (the 'Super'), equivalent to a thousand Hiroshima bombs, represented a catastrophic leap in destructive power, making previous atomic war scenarios seem mild and leading to the complete vaporization of targets. 
  • Military strategy evolved from targeting cities to a 'counter-force' strategy endorsed by Curtis LeMay, advocating for preemptive strikes against Soviet nuclear capabilities, which established the dangerous precedent for 'launch on warning' scenarios. 

Segments

Debating Atomic Bomb Necessity

(00:04:24)
  • Key Takeaway: The use of atomic weapons against Japan is heavily debated, with evidence suggesting Japan’s military leadership had already decided to end the war before the bombings.
  • Summary: The Strategic Bombing Survey concluded that Japan would have surrendered by the end of 1945 even without the atomic bombs or Soviet entry. Attributing the surrender solely to the bombs conveniently allowed Japan to avoid Soviet post-war involvement and partition, similar to Germany. Furthermore, official casualty estimates for a ground invasion were potentially inflated, undermining the primary justification for the bombings.
Groves Lies on Radiation Effects

(00:14:02)
  • Key Takeaway: Manhattan Project head General Leslie Groves deliberately lied to the Senate, claiming radiation poisoning was a ‘very pleasant way to die’ to minimize the horror of atomic weapons.
  • Summary: Groves engaged in a cover-up to make nuclear weapons more palatable to the American public and secure funding for future programs. This lie was contradicted by decades of prior knowledge regarding the horrific effects of radiation poisoning on exposed individuals. This minimization effort was part of a successful marketing campaign to normalize the bomb.
LeMay’s Post-War Nuclear Vision
Copied to clipboard!
(00:16:34)
  • Key Takeaway: Curtis LeMay immediately launched a media blitz post-WWII, echoing Giulio Douhet’s theories, arguing that an unhindered and unchained Air Force centered on nuclear power was the only military future.
  • Summary: LeMay advocated for an Air Force capable of immediate retaliation using atomic power, setting the stage for the concept of deterrence. His insistence that aerial nuclear attacks could not be completely stopped echoed earlier bomber theorists, but became more relevant with nuclear weapons. This mindset led to plans for continuous airborne nuclear patrols.
Deterrence and RAND Corporation

(00:21:35)
  • Key Takeaway: By late 1945, LeMay was already formulating deterrence theory, which required a constant, ready nuclear force, leading the Air Force to establish the RAND Corporation for long-term scientific studies.
  • Summary: The logic of deterrence meant that if an attack couldn’t be stopped, retaliation was the only outcome, creating a contradiction in protecting the country. The Air Force founded RAND (Research ANd Development) to study future scientific projects, immediately leading to proposals like a ‘death ray.’ This period saw the US rely on its nuclear monopoly to reduce conventional forces while guarding Western Europe.
Korean War Bombing Campaign

(00:43:04)
  • Key Takeaway: During the Korean War, Curtis LeMay’s SAC deliberately shifted bombing strategy to target civilian areas to inflict ‘pain’ after precision munitions ran out, killing approximately 2 million North Korean citizens.
  • Summary: The failure of precision bombing to win the war led LeMay to order increased attacks on civilian targets, mirroring the WWII strategy of breaking morale through mass destruction. This massive civilian death toll failed to break North Korean morale, demonstrating the ineffectiveness of this tactic. Furthermore, the focus on the SAC after WWII left conventional ground troops ill-equipped when the war began.
MacArthur’s Extreme Nuclear Plan

(00:49:50)
  • Key Takeaway: General Douglas MacArthur proposed using 30 to 50 tactical nuclear bombs in Korea and laying a radioactive cobalt barrier along the Chinese border to prevent reinforcements, a plan President Truman rejected.
  • Summary: MacArthur’s extreme proposal demonstrated the dangerous mindset of military leaders eager to use nuclear weapons during the conflict. Truman’s refusal to authorize this plan, leading to MacArthur’s dismissal, affirmed civilian control over the military’s nuclear authority. During this period, the US also accidentally crashed a B-29 carrying a nuclear weapon near a military trailer park, highlighting the risks of deployed nuclear assets.
MacArthur’s Insane Nuclear Plan

(00:54:17)
  • Key Takeaway: MacArthur proposed using radioactive cobalt to permanently irradiate the Korean border to block Chinese reinforcements.
  • Summary: MacArthur planned to lay a belt of radioactive cobalt behind the army to make it impossible for Chinese forces to cross into Korea for generations. Truman refused this plan, leading to MacArthur’s public criticism of the president and his subsequent removal from command. The Korean War concluded without further nuclear explosions, which the host notes was a positive outcome.
Nuclear Custody and Stockpile Growth

(00:55:36)
  • Key Takeaway: The US moved nearly 90 nuclear weapons into Europe early in the Korean War, keeping nuclear cores separate from casings for safety.
  • Summary: During the Korean War, the US moved almost 90 nuclear weapons into Europe due to fears of a wider communist invasion. For safety, the Atomic Energy Commission kept the nuclear cores in the US, airlifting them only when needed. This period saw the military gain direct custody of weapons, starting with Strategic Air Command (SAC) in Guam.
Thermonuclear Bomb Development

(01:00:04)
  • Key Takeaway: By 1951, the US stockpile exceeded the number deemed capable of destroying civilization, prompting work on the hydrogen bomb (’the Super’).
  • Summary: The US stockpile grew from 299 to 438 weapons by 1951, surpassing the internal estimate for civilizational destruction. Thermonuclear bombs work by using a nuke to initiate nuclear fusion, resulting in vastly greater explosive power than fission bombs. The prototype thermonuclear weapon designed by Richard Garvin had a 10.4 megaton capacity, equivalent to 1,000 Hiroshima bombs.
Fermi’s Warning and Test Aftermath

(01:03:17)
  • Key Takeaway: Enrico Fermi warned Truman against testing the hydrogen bomb, calling it an ’evil thing’ that endangered humanity, but the test proceeded.
  • Summary: Fermi, Garvin’s mentor, begged Truman not to test the H-bomb because its limitless destructiveness was a danger to all humanity. The first thermonuclear test, Ivy Mike, detonated in November 1952, vaporized the island of Iluge Lab in the Marshall Islands. Truman lamented that future wars would extinguish millions, despite his role in enabling such weapons.
Project Vista and SAC Strategy

(01:06:18)
  • Key Takeaway: Project Vista suggested tactical nukes for battlefield use, but Curtis LeMay’s SAC favored a counter-force strategy targeting Soviet nuclear infrastructure.
  • Summary: Project Vista proposed using low-yield tactical nuclear weapons on the battlefield to replace manpower and avoid nuking European cities. Curtis LeMay opposed this, arguing that winning required striking first and hard against Soviet nuclear capabilities (counter-force strategy). This shift marked the origin of ’launch on warning,’ increasing the risk of accidental nuclear war.
Eisenhower’s Compromise and Army Lobbying
Copied to clipboard!
(01:10:01)
  • Key Takeaway: Eisenhower adopted both tactical nukes for the Army and strategic thermonuclear weapons for SAC, leading to massive stockpile expansion.
  • Summary: Eisenhower decided the US needed both tactical weapons for ground forces and strategic thermonuclear weapons for immediate retaliation, especially after the USSR tested its first H-device in 1953. The US arsenal grew to over 12,000 weapons by 1959, with manufacturing rates exceeding five bombs per day. The Army, facing budget cuts under Eisenhower, lobbied Congress for tens of thousands of nuclear artillery shells and landmines.
