US says no sign Russia mulling nuke use after treaty shelved

UNITED States President Joe Biden yesterday offered fresh criticism of Russia’s suspension of a key nuclear treaty, but stressed there is no indication Moscow is moving closer to actually using an atomic weapon. 

“It’s a big mistake to do that, not very responsible,” Biden told ABC News in an interview in Poland, expanding on brief comments he made before meeting Nato chief Jens Stoltenberg and eastern European leaders in Warsaw.
