While giving his take on the risks of a new global conflict, Russian president, Vladimir Putin recalled Albert Einstein, the renowned physicist and a Nobel Prize winner, who had said: "I do not know with what weapons World War III will be fought, but World War IV will be fought with sticks and stones."
Putin went on to say that “understating of the fact that World War III could be an end of the modern civilization” should deter the world “from any radical and highly dangerous actions that could [threaten] the modern civilization.”
In a reference to the Cold War era, Putin said on a live television programme: "It was a fear of mutual destruction that has always prevented the international actors from any radical moves and forced them to respect each other."
