US Nuclear Weapons Testing: Why Stopped and Why Resuming?

History of Nuclear Testing

• 🇺🇸 The United States initiated the nuclear era with a test in New Mexico in July 1945, followed by atomic bombings of Hiroshima and Nagasaki.
• 🌍 Over five decades, approximately 2,000 nuclear tests were conducted globally, with the US accounting for 1,032.

Reasons for Stopping Tests

• 🤝 The US largely ceased testing after 1996, influenced by the Comprehensive Nuclear-Test-Ban Treaty, which prohibits all nuclear explosions.
• 📣 Public outcry over environmental and humanitarian consequences, coupled with a growing international movement, contributed to the halt.
• 🇷🇺 Russia ratified the treaty in 2000, though it later rolled back its ratification in 2023.

Trump Administration's Rationale for Resumption

• ⚡ President Trump ordered the Pentagon to resume testing nuclear weapons on an "equal basis" with nuclear powers like China and Russia.
• ❓ This decision aims to provide evidence of the capabilities of new weapons and verify the functionality of older ones.
• 🗣️ Trump justified the move by claiming other countries are already conducting tests.

International Implications and Concerns

• 📈 A US testing restart could be perceived by Russia and China as a deliberate display of power, potentially leading to reciprocal actions.
• 🇨🇳 China, having conducted fewer than 100 tests compared to the US and Russia, stands to gain the most from a broken taboo on nuclear testing due to its potential disadvantage in arsenal knowledge.
• ⚠️ Russia has recently conducted tests of a nuclear-powered cruise missile, a nuclear-powered autonomous torpedo, and a nuclear readiness drill.

Global Nuclear Stockpile Trends

• 📉 The global number of nuclear weapons has decreased from a peak of 70,000 during the Cold War to approximately 12,000, with Russia and the US holding the majority.
• 🚀 China's nuclear stockpile has doubled to 600 in the last five years, and all three major powers are modernizing their arsenals.
