Yes, it’s already time to be worried — very worried. As the wars in Ukraine and Gaza have shown, the earliest drone equivalents of “killer robots” have made it onto the battlefield and proved to be devastating weapons. But at least they remain largely under human control. Imagine, for a moment, a world of war in which those aerial drones (or their ground and sea equivalents) controlled us, rather than vice-versa. Then we would be on a destructively different planet in a fashion that might seem almost unimaginable today. Sadly, though, it’s anything but unimaginable, given the work on…

The president of the United States has the sole authority and power to launch the nation’s nuclear weapons. Think about that for a moment.Donald Trump’s emotional, erratic, and unhinged behavior during his first term poses a grave threat to our national security. He has driven uncertainty to an aspect of the presidency that requires predictability: the global nuclear balance. This alone renders Trump dangerously unfit to serve as commander in chief.... But today’s Trump is not the same man he was, even just since he left office in 2021. He is more and more detached from reality. In recent…

This hasn’t exactly been a year of good news when it comes to our war-torn, beleaguered planet, but on Nov. 15, President Joe Biden and Chinese President Xi Jinping took one small step back from the precipice. Until they talked in a mansion near San Francisco, it seemed as if their countries were locked in a downward spiral of taunts and provocations that might, many experts feared, result in a full-blown crisis, even a war — even, God save us all, the world’s first nuclear war. Thanks to that encounter, though, such dangers appear to have receded. Still, the looming question facing both…

National Security Advisor Jake Sullivan spoke to the annual meeting of the Arms Control Association on June 2, and as organization chairman, it was my honor to introduce him. Sullivan said just what needed to be said about the continuing risk of nuclear conflict: that the Biden administration would continue the long U.S. tradition of leadership in finding ways to reduce that danger.In particular, he said the United States is ready – “without preconditions” — to discuss with the Russian Federation how the two countries together could 1) manage nuclear risks, and 2) develop a new nuclear arms…

It has been nearly 80 years since the world entered the nuclear age. But the complex story of the making of the first atomic bomb, the decisions US leaders made to use these terrible new weapons on cities, and the post-war policy missteps that opened the door to the dangerous Cold War arms race are all now starting to fade from public consciousness.The existence of nuclear weapons and the dangers they pose, while well-known and widely feared, are accepted by far too many of those living in one of the world’s nine nuclear-armed countries as part of their “normal” daily lives.A new survey …

Russia’s brutal full-scale invasion of Ukraine has killed thousands of people and displaced millions of civilians. Ukrainian cities have been leveled and villages have been turned into wastelands. U.S. and allied diplomatic, military, and intelligence support to Ukraine, including over $40 billion in security assistance since the war began, is essential to its defense and an eventual end to the conflict.However, providing some types of lethal U.S. and European military assistance to Ukraine would be escalatory, counterproductive, and only further increase the dangers to civilians caught in…

After months of ratcheting up its nuclear activities while negotiations remain stalled, Iran took a small, limited step toward deescalation in May. Iran’s recent willingness to work with the International Atomic Energy Agency (IAEA) to increase transparency on its nuclear program could help open diplomatic space for additional steps toward decreasing tensions and rolling back Iran’s nuclear advances. The United States should take advantage of this limited window, given the growing risk posed by Iran’s nuclear program and the lack of progress in restoring the Joint Comprehensive Plan of Action…

At a meeting of the G7 nations this week in Hiroshima, the first city destroyed by the bomb, President Joe Biden and other leaders have a chance to begin addressing the long-standing problem of states threatening to use nuclear weapons. Russia’s nuclear threats of the past year in support of its invasion of Ukraine have flashed for all to see a core purpose of nuclear arsenals: coercion and intimidation. At this historic gathering, Biden and his counterparts need to act on Japanese Prime Minister Fumio Kishida’s proposal that the G7 “demonstrate a firm commitment to absolutely reject the…

On the 75th anniversary of the atomic bombing of Hiroshima, during the 2020 U.S. presidential campaign, Joe Biden pledged to “restore American leadership on arms control and nonproliferation…and work to bring us closer to a world without nuclear weapons.” This month’s summit of the Group of Seven (G7) in Hiroshima, the site of the first atomic attack that killed more than 140,000 men, women, and children in 1945, provides President Biden with a historic and timely opportunity to do so.To support America’s Japanese allies, Biden and the other leaders will need to acknowledge the horrors of…

What will happen when China invades Taiwan, as so many in Washington believe is inevitable? To answer that question, the House Select Committee on the Chinese Communist Party, an entity created at Speaker Kevin McCarthy’s behest in February, conducted a “tabletop exercise” involving a simulated attack of this sort on April 19. No official report on the closed-door exercise has been made public, but participants indicated that the outcome of such an encounter would prove catastrophic for all parties involved. Committee members were confronted “with the potential for death and destruction on…
