If you listen to President Trump’s cheering section, he is responsible for “the most significant United States foreign policy shift in a generation.” That braggadocio is from a collection of speeches by administration officials about China released by soon-to-be-former national security adviser Robert C. O’Brien. “We are no longer turning a blind eye to the People’s Republic of China’s conduct,” he writes, “nor are we hiding our criticism of its Communist Party behind closed doors.” He even absurdly compares the administration’s anti-Beijing bombast to George Kennan’s brilliant dissection of Soviet conduct in the 1946 “Long Telegram.”
