The Economist: “The cold war, in which America and the Soviet Union menaced each other with tens of thousands of nukes, was scary enough. In the new age America confronts not just Russia but also China.”
“New weapons—among them hypersonic missiles that are hard to detect and shoot down, and space and cyber weapons that threaten command-and-control systems—may unsettle the nuclear balance. Worse, decades of arms-control agreements may end by 2026. A new nuclear-arms race looms. Many think that it has already started.”
