That U.S.-led global order has enabled 70 years of prosperity. It rests on market-oriented regimes of trade liberalization, increased capital mobility, and appropriate social-welfare policies; backed by American security guarantees in Europe, the Middle East, and Asia, through NATO and various other alliances.
Trump, however, may pursue populist, anti-globalization, and protectionist policies that hinder trade and restrict the movement of labor and capital. And he has cast doubt on existing U.S. security guarantees by suggesting he will force America’s allies to pay for more of their own defense. If Trump is serious about putting “America first,” his administration will shift U.S. geopolitical strategy toward isolationism and unilateralism, pursuing only the national interests of the homeland.
