An unearthly spectacle – The untold story of the biggest nuclear bomb (2021)

Documentaries and Visualizations of Nuclear Tests

• Several comments recommend documentaries and declassified test footage, noting they are partly propaganda but still powerful in showing what detonations look like.
• A 1.5 megaton RDS‑4 test video is cited; viewers describe it as terrifying despite being “small” by modern standards.
• The article’s scrolling bomb-size graphic is praised for conveying how absurdly large Tsar Bomba was.

Russian Nuclear Arsenal, Corruption, and MAD

• Some argue Russian corruption may degrade weapon reliability, but others say even a small functioning fraction would be catastrophically sufficient.
• There is broad agreement that Russia remains a serious nuclear threat and that “testing” its weakness would be reckless.
• Commenters discuss the continuing relevance of mutually assured destruction (MAD), especially as a constraint on NATO in Ukraine.

Diplomacy, War, and the Ukraine Conflict

• One side claims “there is no diplomacy” when a leader is set on war, citing Ukraine as an example.
• Others counter that diplomacy can’t magically prevent all wars and works best over long time horizons, sometimes invisibly.
• Debate centers on whether the West’s goal is Ukraine’s outright victory or simply preventing its defeat, with some suggesting the US wants Russia weakened but not collapsed.
• There is disagreement on whether more robust support would topple Putin or just increase risk of escalation.

Nuclear Deterrence, Small States, and North Korea

• Tsar Bomba and similar tests are seen as examples of nationalism, fear, and technology driving arms races (India–Pakistan, China, etc.).
• North Korea is cited as a regime that sacrificed development and endured famine to obtain nukes, arguably ensuring its survival compared to Iraq or Libya.
• Some argue Ukraine would not have been invaded if it had retained nuclear weapons; others reference counterexamples like Israel, India–Pakistan skirmishes, and the UK’s Falklands war.

Doomsday Weapons and Existential Risk

• The discussion highlights US concepts like multi‑gigaton “Sundial” bombs and Soviet “Dead Hand” systems as literal doomsday machines.
• Commenters compare such devices to large volcanic eruptions and debate whether fallout or fire-induced “nuclear winter” is the main global killer.
• Several reflect philosophically on humanity’s capacity to build planet‑threatening weapons and how hypothetical alien observers might judge that behavior.
