The Deep Roots of Trump’s Isolationism

Charles Kupchan

The mainstream U.S. foreign policy establishment views former President Donald Trump as a dangerous neo-isolationist, completely out of step with American ideals and interests. Internationalists at home and abroad shudder at the prospect of Trump’s potential reelection in November, fearing that he would dismantle the liberal order that the United States and its allies have built and defended since World War II.

Such fears are justified; Trump may indeed seek to do away with at least some core elements of the U.S.-led liberal order. But to portray his “America first” approach as a dark deviation from the American experience is to misunderstand its deep historical and ideological roots, as well as its considerable political appeal. Trump’s statecraft is a response to a changing world and to demand signals from the U.S. electorate, not a capricious effort to take apart the world that the United States made.

None of this is to deny that Trump’s return to office could be disastrous. At home, he may well imperil American democracy. Abroad, Trump’s mere reelection would set the world on edge. U.S. allies would have to face the reality that their security guarantor—the globe’s premier power—has been beset by intractable political dysfunction; they would have no choice but to question Washington’s long-term reliability and make other plans. Meanwhile, autocrats would be emboldened and the cause of democracy everywhere debilitated.
