Precarious Multilateralism Seizes CTBTO Nuclear-Test-Ban Organization

By Stephanie Liechtenstein*, Passblue

VIENNA (IDN) – For the first time in its 24-year history, state parties to the Comprehensive Test Ban Treaty, a multilateral agreement that bans all nuclear testing worldwide, have taken a controversial decision by a two-thirds majority. Decisions in the treaty’s body are usually taken by consensus.

The majority decision on October 19 was focused on whether countries with unpaid dues could vote in the election of the next executive secretary of the Preparatory Commission to the Comprehensive Test Ban Treaty Organization. (The body is not part of the United Nations but has a cooperative agreement with it.)

Eminent Persons Warn Against Any Demonstration Nuclear Test Explosion

By Reinhard Jacobsen

VIENNA (IDN) – Members of the CTBTO Group of Eminent Persons (GEM) have expressed "deep concern about credible press reports" that senior U.S. officials have discussed the possibility of conducting "a demonstration nuclear test explosion".

They warn that if carried out, it would break the global moratorium on nuclear weapon test explosions and severely undermine the Comprehensive Nuclear Test Ban (CTBT) regime, established to help detect and deter nuclear weapon test explosions anywhere in the world.

WASHINGTON, DC (IDN | Arms Control Association) – Everybody knows that nuclear weapons have been used twice in wartime and with terrible consequences. Often overlooked, however, is the large-scale, postwar use of nuclear weapons: At least eight countries have conducted 2,056 nuclear test explosions, most of which were far larger than the bombs that leveled Hiroshima and Nagasaki. The United States alone has detonated more than 1,030 nuclear explosions in the atmosphere, underwater, and underground.
