What do we ment by CTBT

Answer 1

It is widely understood that nuclear weapons have only been used twice in wartime and with terrible consequences. Often overlooked is the fact that they have been “used” elsewhere—through more than 2,000 nuclear test explosions by at least eight countries since 1945.

These nuclear test explosions have been used to develop new nuclear warhead designs and to demonstrate nuclear weapons capabilities by the world’s nuclear-armed states. The tests, particularly the atmospheric detonations, have negatively affected the lives and health of millions of people around the globe.  In response, ordinary citizens, scientists, legislators, and government leaders have pursued a multi-decade effort to bring into force a global verifiable comprehensive nuclear test ban.

A global halt to nuclear weapons testing was first proposed in 1954 by Indian Prime Minister Jawaharlal Nehru as a step toward ending the nuclear arms race and preventing nuclear proliferation. A ban on nuclear testing has been a key national security objective of the United States since the late-1950s, when President Dwight D. Eisenhower initiated U.S.-UK-USSR comprehensive test ban negotiations.
