U.S. Energy Secretary Chris Wright clarified that the U.S. would not engage in explosive testing. Secretary Wright said, "The tests we're talking about right now are system tests. These are not nuclear explosions. These are what we call non-critical explosions." He added, "With our science and our computation power, we can simulate incredibly accurately exactly what will happen in a nuclear explosion. Now we simulate 'what were the conditions' that delivered that, and as we change bomb designs, 'what will they deliver?'" The U.S. has not conducted nuclear testing in 33 years. |
