Biden: Putin nuclear threat is 'real'

President Joe Biden said on Monday the threat of Russian President Vladimir Putin using tactical nuclear weapons is "real" – days after denouncing Russia's deployment of such weapons in Belarus.

On Saturday, Biden called Putin's announcement that Russia had deployed its first tactical nuclear weapons to Belarus "absolutely irresponsible."

"When I was out here about two years ago saying I worried about the Colorado river drying up, everybody looked at me like I was crazy," Biden told a group of donors in California on Monday.

"They looked at me like when I said I worry about Putin using tactical nuclear weapons. It's real," Biden said.

Last week, Belarusian President Alexander Lukashenko said his country has started taking delivery of Russian tactical nuclear weapons, some of which he said were three times more powerful than the atomic bombs the U.S. dropped on Hiroshima and Nagasaki in 1945.
