If the United States pulls back, the world will become more dangerous

EIGHTY YEARS ago Japan bombed Pearl Harbour. It was a grave error, bringing the world’s mightiest country into the war and dooming the Japanese empire to oblivion. A clear-sighted Japanese admiral supposedly lamented: “I fear all we have done is to awaken a sleeping giant and fill him with a terrible resolve.”Today is peaceable, rich and innovative. It was the Japanese who rebuilt their country, but their task was made easier by the superpower that defeated them. Not only was America midwife to a liberal, capitalist democracy in Japan; it also created a world order in which Japan was free to trade and grow. This order was not perfect, and did not apply everywhere. But it was better than anything that had come before.
