The Emptiness of the Rubio Doctrine

But what all these doctrines had in common was that they constituted an effort to define, and answer, the specific challenge of a given time. For Monroe, it was hemispheric independence. For Truman, it was communist expansion. For Carter, it was threats to America’s oil supply.

 

.. Historically, foreign-policy doctrines have been the opposite of “timeless.” They represent efforts to further American interests and ideals by offering a specific response to a specific geopolitical reality. Every president wants the United States to be strong, prosperous, and moral. Doctrines are supposed to outline a strategy for achieving those goals. They are not the goals themselves.

.. Truman’s “containment” doctrine and Reagan’s doctrine of “rollback” each had problems. But at least they were aimed at a specific enemy. Rubio can’t lay out a doctrine like that today because the two enemies he and other Republicans talk about most—Iran and ISIS—are only linked in the conservative imagination. On the ground, they’re at war.
