Eighteen months into Donald Trump’s presidency, the nature of his foreign policy continues to elude most observers. The problem is not, as some admirers claim, that he is playing an elaborate strategic game that his critics can’t grasp. Nor is it, as some detractors believe, that Mr. Trump is simply a creature of impulse with no fixed views. The president’s approach to foreign policy may well fail—indeed, there is a case it deserves to. But a Trump doctrine exists, and neither friends nor foes can afford to remain blind to it.
Mr. Trump is hard to understand not because he is deep but because he is different. American presidents since the 1940s have primarily sought to conserve the post-World War II order. Mr. Trump, on the other hand, is a revisionist who wants to alter the terms of the world system in America’s favor. From the president’s perspective, America’s superior military strength and its large trade deficit provide important advantages in international politics. Mr. Trump wants to boost America’s military edge while using military and economic tools to persuade other powers to accept his revisions to the world system.
Mr. Trump respects China as a serious long-term rival but believes that its economy depends more on Sino-American trade than the U.S. economy does. This is partly because China is much poorer than the U.S. on a per capita basis. Further, Mr. Trump believes that America’s bilateral trade deficit means that the current arrangement heavily favors China, and that China would be less able to withstand a disruption to that relationship.
