Realistic, creative vulnerability assessment and testing are critical to finding and fixing nuclear security weaknesses and avoiding over-confidence. Both vulnerability assessment and realistic testing are needed to ensure that nuclear security systems are providing the level of protection required. Systems must be challenged by experts thinking like adversaries, trying to find ways to overcome them. Effective vulnerability assessment and realistic testing are more difficult in the case of insider threats, and special attention is needed. Organizations need to find ways to give people the mission and the incentives to find nuclear security weaknesses and suggest ways they might be fixed. With the right approaches and incentives in place, effective vulnerability assessment and testing can be a key part of achieving and sustaining high levels of nuclear security.

Participants at the final Nuclear Security Summit in 2016 agreed on “action plans” for initiatives they would support by five international organizations and groups—the International Atomic Energy Agency, the Global Initiative to Combat Nuclear Terrorism, INTERPOL, the United Nations, and the Global Partnership Against the Spread of Weapons and Materials of Destruction. These institutions were supposed to play key roles in bolstering ongoing nuclear security cooperation after the summit process ended. The action plans were modest documents, largely endorsing activities already underway, and there have been mixed results in implementing them. To date, these organizations have not filled any substantial part of the role once played by the nuclear security summits.

Civil society has played a very important role in nuclear security over the years, and its role could be strengthened in the future. Some nuclear organizations react against the very idea of civil society involvement, thinking of only one societal role—protesting. In fact, however, civil society has played quite a number of critical roles in nuclear security over the years, including highlighting the dangers of nuclear terrorism; providing research and ideas; nudging governments to act; tracking progress and holding governments and operators accountable; educating the public and other stakeholders; promoting dialogue and partnerships; helping with nuclear security implementation; funding initial steps; and more. Funding organizations (both government and non-government) should consider ways to support civil society work and expertise focused on nuclear security in additional countries. Rather than simply protesting and opposing, civil society organizations can help build more effective nuclear security practices around the world.

Neither the United States nor Iran wants to go to war. That’s the good news. The bad news is that in the fog of crisis — similar in many ways to the fog of war — the danger of inadvertently stumbling into war is dangerously high.

Belfer Center experts weigh in on potential impacts of the U.S. killing of Gen. Qassem Soleimani.

In a dangerous world, every US use of military force should be backed up by a careful calculation of risks and a strategy to cope with the adversary’s response. Neither risk-balancing nor strategy is apparent in President Trump’s decision to kill Major General Qassem Soleimani, leader of the Quds Force of Iran’s Revolutionary Guard. With that killing — and Iran’s announcement it would exact a “harsh revenge” — there is a real danger the Middle East will slide even further into the fires of war.

The House of Representatives is moving inexorably toward impeaching President Trump for what he has said and done in his dealings with Ukraine. But what the president hasn’t done or said is almost as appalling, revealing a president who cares only about his personal interests, not America’s interests.

From the 1950s, after a brief stint at the fledgling United Nations, Timerbaev was directly supporting Soviet Foreign Minister Andrei Gromyko on nuclear weapons issues. (He remembered drafting the first Soviet proposal for a fissile material cutoff treaty in 1958.)  Preventing nuclear annihilation became his consuming, life-long passion. He retired from the Foreign Ministry just as the Soviet Union was collapsing, resigning as permanent representative to the international organizations in Vienna, including, of course, the International Atomic Energy Agency (IAEA).

South Korean fighter jets fired over 300 warning shots at a Russian Air Force A-50 Mainstay Airborne Early Warning aircraft on July 23 after the Russian plane twice violated South Korea’s airspace above the East Sea, according to South Korean authorities cited by The Aviationist. Earlier that day, Russian and Chinese bombers had conducted their first long-range joint air patrol in the Asia-Pacific. Russia’s Defense Ministry said there had been “no violations of airspaces of foreign countries” in its joint patrol with China, according to the New York Times, and Russian diplomats in Seoul reportedly complained of inaccuracies in the official comments from South Korea.

Russia Matters asked some members of the Belfer Center’s Russia team for their take on the developments.

Right now, everything both sides do to strengthen their defenses looks to the other side like preparation for attack.
