The next U.S.-Russia nuclear arms race
"A new nuclear policy issued by the Trump administration on Friday ... is touching off a new kind of nuclear arms race. This one is based less on numbers of weapons and more on novel tactics and technologies, meant to outwit and outmaneuver the other side," the N.Y. Times' David E. Sanger and William J. Broad write at the bottom of A1.
Why it matters: "The report describes future arms control agreements as 'difficult to envision' in a world 'that is characterized by nuclear-armed states seeking to change borders and overturn existing norms,' and in particular by Russian violations of a series of other arms-limitation treaties."
