Debates connected to the culture war, including even on such amorphous issues as the West’s slide into spiritual nihilism or the loss of its inner will, are directly relevant to international politics and even international security. Western strategic thinkers must take these issues into account just as analysts in Beijing or Moscow do. To do otherwise would be a dangerous mistake. The Chinese Communist Party under Xi Jinping has made cultivating a civilizational “spirit of struggle” central to its mission while judging the West’s loss of the confidence to defend itself to be a fact of historic significance. At least for the sake of their own defense, Westerners may want to explore the possibility of thinking along similar lines.
