Strains with China are "the biggest problem for America, the biggest problem for the world," Kissinger told the McCain Institute's Sedona Forum on global issues. "Because if we can't solve that, then the risk is that all over the world a kind of cold war will develop between China and the United States."
While nuclear weapons were already large enough to damage the entire globe during the Cold War, he said advances in nuclear technology and artificial intelligence -- where China and the United States are both leaders -- have multiplied the doomsday threat. "For the first time in human history, humanity has the capacity to extinguish itself in a finite period of time," Kissinger said.
