 So Kissinger's big move was triangulation, right? Like saying there were three great superpowers in the world, population, military, et cetera. And they were the United States, Soviet Union, then Soviet Union, and China. And sent Nixon to China and said, listen, if we can make sure there's still a wedge between Russia and China, they sort of fear each other. And if we're a little bit friendlier to them, that'll help keep Russia in check, help keep the Soviet Union in check.
