As reported by the UK Telegraph:
"Prominent Russian TV host Dmitry Kiselyov, has said in a broadcast that "Russia is the only country in the world able to turn the USA into radioactive ashes". His inflammatory words are a step-up from the flurry of diplomatic discussions regarding the ongoing crisis in Ukraine.
Standing in the studio, in front of an image of a large mushroom cloud and the words 'Into radioactive ashes', Dmitry Kiselyov's news report sends a worrying message to the US."
Not only do Kiselyov's words pour gasoline onto the fire of the conflict over Crimea, it also raises the specter that arms control and non-proliferation achievements of past years and decades could be rolled back over the deepening conflict between Ukraine and Russia.
