At a virtual forum hosted by the McCain Institute a week ago, Henry Kissinger sounded real worried about the way the United States’ relations with China are going these days. And when the 97-year-old former diplomat and acclaimed political theorist says he is worried, the world must pay attention. He is worried, he said, because the current crisis between the two economic superpowers could, if not handled rationally, lead to a war of annihilation. “For the first time in human history, humanity has the capacity to extinguish itself in a finite period of time,” he said. And that is incredibly significant coming from a well-known realist like Kissinger.
