“America First” was always more of a campaign slogan than a strategy. But if the Trump doctrine has materialized in any coherent way, it’s a reflexive rejection of the hawkish foreign policy of the Republican Party’s recent past.

President Trump controversially attempted to pull American forces out of Syria, tolerated Russian protection of Venezuelan dictator Nicolas Maduro, and let Kim Jong Un waffle on weapon agreements. “America First” points to a less interventionist ideal.
