How Every Country Got Nuclear Weapons Explained

Overview

The video traces how nuclear weapons spread from the United States’ first bomb to 10 countries that have developed their own arsenals. It emphasizes secrecy, intelligence operations, and changing alliances, while also covering states that hosted foreign nukes, countries that nearly crossed the threshold, and the likelihood of additional entrants.

Main narrative: The 10-country nuclear race

1938–1945: Foundations and the U.S. lead

• 1938: German scientists discover the weapon-relevant potential of nuclear fission.
• 1939: Einstein warns the United States about weaponization.
• Manhattan Project: The U.S. (with UK and Canada) races Germany, with heavy U.S. investment.
• 1945:
  • The U.S. conducts the Trinity test.
  • The U.S. uses atomic bombs on Japan (“Fat Man” and “Little Boy”).
• The video portrays the U.S. as informing Stalin it intends to use the weapon—despite Stalin already pursuing a bomb through espionage.

Soviet Union (2nd): Accelerated development + distrust of stolen designs

• The Soviets begin earlier (as early as 1941) after suspecting Western work.
• Spies provide information, but Soviet leadership worries about misinformation/double agents, so they rely more on:
  • independent research, and
  • captured German scientists.
• 1949: The RDS-1 test occurs in Kazakhstan.
• This ends U.S. monopoly and intensifies the Cold War arms race.

United Kingdom (3rd): Ally turned competitor

• The UK starts “Tube Alloys” in 1940, using displaced European scientists.
• During WWII, the UK shares work with the U.S.; after the U.S. succeeds, the agreement effectively ends.
• The UK resumes its own program and tests “Operation Hurricane” (1952).

U.S. thermonuclear leap + UK/U.S. agreement break (context)

• After learning the Soviets obtained bombs sooner than expected, the U.S. pursues thermonuclear (fusion) weapons.
• Oppenheimer and others warn about dangers, but Truman approves “Ivy Mike” (1952).
• The Soviets test theirs in 1955 (RDS-37); the UK follows in 1957.
• The U.S. then resigns the nuclear agreement with the UK.

France (4th): Independence strategy

• France’s post-WWII effort is framed as driven by deterrence and maintaining great-power independence.
• Charles de Gaulle is highlighted as leading the effort.
• 1960: France tests “Gerboise Bleue.”
• 1968: France develops/testing a hydrogen bomb.

China (5th): Soviet help withdrawn; rapid breakthroughs

• China initially receives Soviet support, but relations sour when the USSR criticizes China’s direction and assistance is withdrawn.
• China continues alone while dealing with the Great Leap Forward and Cultural Revolution.
• 1964: First atomic bomb (Project “596”).
• Only 32 months later: a hydrogen test—presented as the fastest progression globally.

Israel (6th): Undeclared arsenal + leaked evidence

• The video describes Israel as the only state that does not officially acknowledge having nuclear weapons.
• It focuses on secret development tied to French cooperation and a Negev facility.
• JFK is portrayed as pressing for inspections; Israel delays and conceals components.
• A major disclosure is 1986’s Mordechai Vanunu leak (photos/documents), leading to imprisonment and ongoing restrictions.
• The video claims Vanunu’s leaks suggest Israel may have thermonuclear capability.

India (7th): “Peaceful” test + slow or partial weaponization

• India seeks deterrence and accelerates after conflict with China (1962).
• 1974: First nuclear test (“Smiling Buddha”), widely condemned internationally and linked to sanctions.
• The video suggests India stops short of full weaponization at first, though later seeks capability.
• It frames full “activation” as not finalized until the 1990s.

South Africa (8th): Ambiguous weapons, near-test, then full dismantlement

• South Africa has large uranium reserves, initially linked to peaceful reactor supply.
• Political isolation and security concerns shift interest toward weapons.
• 1977–1979: A planned test is interrupted after satellite detection and international pressure (the Vela incident is described as likely a joint test involving Israel + South Africa).
• By the mid-1980s, the video describes South Africa as having six bombs (with Israel-linked assistance suggested).
• In the 1990s, it portrays South Africa as dismantling and admitting it had nukes first among known cases; enriched material is secured, though a 2007 intrusion is reported.

Pakistan (9th): “Grass/leaves” vow + proliferation networks

• Pakistan begins its program after defeats by India, including leading to Bangladesh in 1971.
• After India’s 1974 test (“Smiling Buddha”), Pakistan’s effort accelerates.
• The video emphasizes A.Q. Khan stealing enrichment knowledge from Dutch facilities and links to China for expertise/material/blueprints.
• 1998:
  • India tests.
  • Pakistan responds shortly after—both framed as completing nuclear entry.
• Pakistan’s strategy is described as first-use permissive, contrasted with India’s no-first-use posture—shaping regional deterrence dynamics.

North Korea (10th): Early assistance, sanctions/failed deal, multiple tests

• Early nuclear research is described as involving Soviet-era training/help for peaceful facilities.
• North Korea refuses sustained external weapon assistance, draws on its own uranium reserves, and gradually turns to weapons.
• It later signs the NPT, but the video portrays it as delaying inspections while progressing secretly.
• A U.S. offer (light-water reactors) collapses due to mistrust; North Korea withdraws from the NPT and resumes weapons development.
• 2006: first test (small yield, possibly malfunctioning).
• Later tests in 2009, 2013, and 2016–2017, with claims of higher-yield and thermonuclear capability.

Other major points: hosted nukes, near-misses, and future risk

Nukes hosted under alliances (Cold War legacy)

• The U.S. is described as deploying weapons in multiple European countries and allied territories (some later removed).
• The Soviet Union is described as storing weapons in several Soviet republics; most are dismantled after the USSR collapses.
• The video claims Russia again supplied Belarus in 2023.

States that came close but stopped

• The video mentions countries such as Iraq, Syria, Iran, Libya, and others as having significant progress, but being thwarted by destruction/sabotage and international pressure.
• Iran is framed as the most likely next nuclear-adjacent case, with Israel portrayed as strongly motivated to prevent it.

Possible future entrants

• Saudi Arabia: implied willingness to pursue capability if Iran obtains it.
• Japan: framed as technically capable due to advanced nuclear technology and enriched uranium stockpiles, but constrained by pacifist policy.
• Argentina and Brazil: described as close due to infrastructure and know-how.

Treaties and deterrence via submarines

• The video lists nuclear arms control and nuclear-weapon-free zone treaties (e.g., for Africa, South Pacific, Central Asia, Southeast Asia, Antarctica).
• It argues treaties don’t fully eliminate risk because many nuclear states keep weapons on submarines:
  • hard to detect,
  • hard to destroy,
  • which strengthens deterrence and makes secret development extremely difficult.
