RT news anchor Dmitry K. Kiselyov told viewers Sunday that Russia is the only country on Earth capable of turning the U.S. into “radioactive dust” by the strength of its nuclear program.

With a mushroom cloud graphic behind him, Kiselyov, one of the country’s most influential state media representatives, also claimed President Obama’s hair had turned gray because of the stress of dealing with Russia and President Vladimir Putin.

A report by AFP quoted Kiselyov as saying Russia would turn the U.S. to “radioactive ash.”
