Summary of the 2018 Nuclear Posture Review

In an article in Lawfare, CTBTO Youth Group member Brenna Gautam summarizes the key takeaways from the Nuclear Posture Review (NPR) and comments on the lowered threshold for employing nuclear weapons. She further makes a point of the 20 kiloton limit classifying nuclear weapons as low yield, a limit that also classifies the denotation in Hiroshima – with its 15 kiloton yield – as a low yield nuclear weapon.

On the United States’ position toward international treaties like the CTBT, Gautam reiterates that according to the NPR, although the U.S. does not seek to ratify the CTBT, it will not resume nuclear testing unless deemed necessary and it also calls on other nuclear weapon states to declare or maintain a moratorium on nuclear tests.

Kick Off To A Nuclear Race Threatening Doomsday


In an article from In Depth News, Sergio Duarte – GEM member of the 1995 Nobel Peace Laureate Pugwash Conferences on Science and World Affairs – writes about the Doomsday Clock and the Nuclear Posture Review and the widely different world views that they represent, despite both responding to security concerns and being announced almost simultaneously. Duarte further states that there are important treaties on preventing the proliferation of weapons of mass destruction, like the CTBT, that have not entered into force. He notes that only North Korea has carried out nuclear tests in this century, while all other states are observing a voluntary moratorium, and further touches upon the U.S.’s continued support of the CTBTO, the IMS and IDC, despite of its unwillingness to ratify the CTBT.

On 7 January, under the Slovakian Chairmanship, the OSCE held a Forum for Security Co-operation in Vienna. The Forum discussed the 2004 United Nations Security Council Resolution 1540 on preventing the proliferation of weapons of mass destruction, and gave voice to international actors, such as the OSCE and CTBTO, that are supporting the implementation of the resolution. Ambassador Maria Assunta Accili Sabbatini said that the “CTBT is a major building block of the current multilateral disarmament and non-proliferation architecture” while CTBTO Executive Secretary Lassina Zerbo stated that “[t]he strengthened co-operation between the CTBTO and the OSCE can be a force multiplier.” Zerbo went on to express appreciation for the fact that “the OSCE has initiated the concept of a strategic dialogue to address divergent regional and global threat perceptions.” Read the full article here
