Episode Details

Since July 16, 1945, eight nations have detonated nuclear devices — but the official tally depends entirely on who's counting and what they've agreed to count. This episode digs into why the Arms Control Association says 2,056 tests, Wikipedia says 2,121, and SIPRI landed at 2,058, and how a single salvo of five warheads can be recorded as one line item. It also examines the detonations that never made the list at all: subcritical experiments that produce zero yield, the still-unconfirmed 1979 Vela incident, and a 2020 US allegation against China that no independent monitoring system ever flagged. The numbers tell a story — and it's a story about treaties, bookkeeping, and governments deciding what history gets written down.
