Following his opening remarks, Dr. Zerbo and an accompanying panel of experts engaged in a discussion on how the scientific community and international organizations can work together to advance individual and collective goals, particularly as they relate to verifying the dismantlement of a…

A new survey shows that 20 years after the opening for signature of the CTBT, the majority of Americans still support the test ban. This latest survey joins many other polls that have found high American support for the CTBT over the past six decades.This chart, pulled from data from the 2016 poll by Herzog and Baron, was in response to the following question: “Should the US Senate approve a treaty with 164 other countries that would prohibit nuclear weapon test explosions worldwide?”Working with the polling firm YouGov, Stephen Herzog and Jonathan Baron, both Ph.D candidates at Yale…

 The joint statement from the historic June 12 Singapore summit meeting between North Korean leader Kim Jong Un and U.S. President Donald Trump stated that North Korea will “work toward the complete denuclearization of the Korean Peninsula” and the two countries “commit to hold follow-on negotiations.” Assessing whether the summit was a success or a failure will depend in large part on what the follow-on talks accomplish and if the process leads to concrete steps by North Korea to halt and roll back its nuclear weapons program. The indication in the summit document that the United States and…

The Comprehensive Test Ban Treaty Organization (CTBTO) hosted its 2nd CTBT Science and Diplomacy Symposium from May 21 to June 1, 2018 at the Vienna International Center against the backdrop of significant geopolitical developments: the Trump administration’s withdrawal from the Joint Comprehensive Plan of Action (JCPOA), U.S. declaration of a summit meeting with North Korea and deteriorating U.S.-Russia relations. Understandably, the interest of policymakers, scholars and technical experts gathered at the symposium were focused on a few key questions – Will North Korea sign and ratify the…

This op-ed originally appeared in TIME, Jun. 13, 2018. The handshake between President Donald Trump and North Korean leader Kim Jong Un will go down in history. But it’s not yet clear if the summit will produce an equally historic outcome on denuclearization. Despite Trump’s attempts to sell the summit document as a breakthrough, it reiterates a boilerplate commitment to “complete denuclearization of the Korean peninsula,” a pledge that North Korea has made, and broken, before. This vague, aspirational language is a long way from the “comprehensive document” described by Trump in his press…

This op-ed originally appeared in the Bulletin of Atomic Scientists Ahead of US President Donald Trump’s summit with North Korean leader Kim Jong-un, we spoke with young people around the world who saw hope in the summit, and a chance to advance their own work—including the reunion of families divided by conflict, the peaceful reunification of the Korean Peninsula, and a negotiated agreement that would lead toward the denuclearization of North Korea. Captivated by North Korea’s nuclear tests and Trump’s reckless Twitter tirades, the media rarely pick up voices of the next generation. Young…

On the morning of June 12, 1982, as the sun shined down on the green grass in Central Park, people began to gather carrying signs for nuclear disarmament. Throughout the morning, buses arrived from around the country. By the afternoon, nearly every blade of grass was covered. Citizens filled second, third, fifth, sixth, seventh, and Madison avenues. By mid-afternoon, the police estimated that over 750,000 people were in Central Park demanding an end to nuclear weapons. By the end of the day, that number had swelled to 1 million.The rally and subsequent march were organized around the United…

The International Atomic Energy Agency (IAEA) released its quarterly report on Iran’s nuclear program June 6, and, unsurprisingly, the report found that Iran is complying with its commitments under the multilateral deal known as the Joint Comprehensive Plan of Action (JCPOA).The report, finalized May 24, was the first since U.S. President Donald Trump violated the nuclear deal May 8 by reimposing sanctions on Iran, and withdrew the United States from the accord. The report bears out what Iranian officials stated after Trump’s announcement – that Iran would remain within the JCPOA, for now.…

Joint Commission Discusses U.S. WithdrawalRepresentatives from the P4+1 and Iran met in Vienna May 25 to discuss the implementation of the nuclear deal known as the Joint Comprehensive Plan of Action (JCPOA) after U.S. President Donald Trump reimposed sanctions and withdrew from the agreement.While officials from the P4+1 (China, France, Germany, Russia, and the United Kingdom) and Iran have met over the past several weeks, this was the first meeting of the Joint Commission, a body set up by the JCPOA to oversee implementation of the accord, since Trump’s May 8 announcement. The Joint…

Following a late April announcement by Kim Jong Un, North Korea announced on May 24 that it had destroyed its nuclear testing site at Punggye-ri.“Dismantling the nuclear test ground was done in such a way as to make all the tunnels of the test ground collapse by explosion and completely close the tunnel entrances,” a deputy director at North Korea’s Nuclear Weapons Institute said, according to state media.North Korea claimed to destroy the north, south and west portals to the testing site as well as barracks, observation towers and other buildings. The east portal was abandoned shortly after…
