Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

Steven E. Miller writes that U.S. withdrawal from the Intermediate Range Nuclear Forces Treaty offers few benefits and solves no significant security problem, while raising some potential costs and obvious disadvantages.

"From Hiroshima to the Cuban Missile Crisis, from arms races to arms control, from the Cold War and its proxy wars to the 2003 invasion of Iraq and the 2015 deal with Iran, few subjects have so consistently, and so controversially, concerned the American presidency as nuclear weapons have. A dozen men have been responsible for the decision to use the US nuclear arsenal since 1945, and whoever wins the election in November will inherit the responsibility for approximately 4,670 warheads at a time when relations with Russia (holder of 4,500 warheads) have reached a perilous low, a time when support for arms control is perhaps faltering, and a time when nuclear threats abound from the Middle East to the Korean Peninsula..."

"Today and tomorrow, world leaders will gather for what will likely be the final international summit on security for nuclear weapons and the materials needed to make them—a key tool for preventing nuclear terrorism. The last time this group met, at the 2014 Nuclear Security Summit in the Hague, they declared that preventing terrorists from acquiring nuclear weapons or weapons-usable materials remained “one of the most important challenges in the years to come.” Yet, since then, nuclear security has improved only marginally, while the capabilities of some terrorist groups, particularly the Islamic State, have grown dramatically, suggesting that in the net, the risk of nuclear terrorism may be higher than it was two years ago..."

"As world leaders gather for the fourth nuclear security summit this week, in the aftermath of the horrifying terrorist attacks in Brussels, it seems likely that Belgian Prime Minister Charles Michel will have more to say than anyone else — both about real nuclear terrorist dangers and about real steps taken to improve nuclear security...."
