The Doomsday Clock is an internationally recognized design that conveys how close we are to destroying our civilization with dangerous technologies of our own making. First and foremost among these are nuclear weapons, but the dangers include climate-changing technologies, emerging... Read More
Machines exploiting advances in neural networks have demonstrated better-than-human performance on tests they were not programmed to perform. One such advanced program, Google DeepMind, used so-called “deep learning” to train itself to play Atari games at a super-human level.
The author argues that technological barriers to deploying hypersonic missiles will inevitably be overcome, and it is inconceivable that nations such as the United States, China, and Russia will agree to a hypersonic test ban without overcoming those barriers first.
Hypersonic missile technology, if it ever matures, will enable quick strikes over long distances. But critics say that hypersonics are destabilizing—for example, they could be used to attack nuclear installations or could be mistaken for nuclear-armed missiles.
Amid tension between nuclear-armed nations, one side uses antisatellite weapons to disable its adversary's space assets. Is it seeking advantage in a conventional conflict—or preparing a nuclear first strike? In this scenario, the cost of miscalculation could be vast.
The real question in space, the author argues, is not whether individual countries support arms control efforts and desire strategic stability—but rather, how these goals will be pursued, according to which principles, and in pursuit of what priorities.
Turkey’s reaction to a successful deal with Iran will be relief, if not revelry. Iran’s abandonment of its nuclear ambitions spares Turkey from having to divert its resources to military (and possibly, nuclear) spending.
