On October 30, 2025, Donald Trump announced the potential resumption of U.S. nuclear weapons testing.
The announcement raised concerns about the future of the Comprehensive Test Ban Treaty (CTBT) and the global nuclear order.
The New Strategic Arms Reduction Treaty (New START) between the U.S. and Russia is set to expire on February 4, 2026.
China's nuclear arsenal is rapidly expanding, estimated to exceed 1,000 warheads by 2030.
Detailed Insights:
The global nuclear order faces strain due to the potential resumption of nuclear testing and the expansion of nuclear arsenals.
The CTBT, signed by 187 countries, has not entered into force due to a lack of ratification by key nations, including the U.S. and China.
The U.S. has been developing new warheads, including the B61-13 gravity bomb and the W76-2 warhead, while Russia and China are also modernizing their nuclear capabilities.
Resumption of explosive testing could lead to the demise of the CTBT and the unravelling of the Nuclear Non-Proliferation Treaty (NPT) regime.
India, which has observed a voluntary moratorium since 1998, may resume testing to validate its nuclear designs if explosive testing resumes globally.
The UN Secretary General has cautioned against actions that could lead to miscalculation or escalation with catastrophic consequences.
Key Concepts Involved:
Nuclear Non-Proliferation Treaty (NPT): An international treaty to prevent the spread of nuclear weapons and promote disarmament.
Comprehensive Test Ban Treaty (CTBT): A treaty prohibiting all nuclear weapon test explosions.
New START: A nuclear arms reduction treaty between the United States and Russia, limiting strategic nuclear warheads and delivery systems.
