Trump’s nuclear test threat risks upending global test ban regime, Pg18

Key Highlights:

• U.S. President Donald Trump threatened to resume U.S. nuclear weapon testing, potentially ending the global moratorium.
• Russia and China have maintained a moratorium on nuclear testing since the 1990s, though Russia de-ratified the CTBT in 2023.
• The Comprehensive Test Ban Treaty (CTBT), which bans all nuclear tests, has not come into force due to lack of ratification by required countries.
• The U.S. has conducted the most nuclear tests historically (1,030), followed by the Soviet Union (715) and France (210).
• U.S. Secretary of Energy Chris Wright stated the U.S. would conduct "subcritical tests" instead of resuming full nuclear weapon tests.
• Resumption of nuclear testing by the U.S. could trigger a new nuclear arms race involving Russia, China, India, and Pakistan.

Detailed Insights:

• Trump's statement followed Russia's announcement of successful tests of a nuclear-powered cruise missile (Burevestnik) and an undersea torpedo (Poseidon).
• Supporters of nuclear testing in the U.S. argue it is necessary to bolster the country's nuclear deterrent and develop more powerful warheads.
• The 1963 Partial Test Ban Treaty banned nuclear test detonations in the atmosphere, outer space, and underwater, leading to underground testing.
• Underground nuclear tests can cause significant environmental damage, including ecosystem destruction and contamination of soil, air, and water.
• China has reportedly made preparations at Lop Nur to resume testing if the U.S. does, and Russia has stated it will follow suit if the U.S. resumes testing.
• A renewed nuclear arms race could have long-term consequences for humanity, increasing the risk of nuclear conflict and environmental devastation.

Key Concepts Involved:

• Nuclear Deterrent: Maintaining nuclear weapons to discourage attack.
• Comprehensive Test Ban Treaty (CTBT): A treaty banning all nuclear weapon tests.
• Subcritical Test: A test using conventional explosives to compress fissile material without triggering a nuclear explosion.
