How Trump is Reshaping American Foreign Policy
The urge within the commentariat to describe every president’s foreign policy in terms of some clearly defined doctrine is as strong as ever, but Donald Trump presents would-be doctrine-definers with perhaps their toughest challenge yet. This observation is not by itself a criticism of Trump’s policies. Doctrine is overrated. Given the complexities of America’s relationship with the world and the multiplicity of U.S. interests involved, any set of policies that fits neatly into a simply defined doctrine is apt to be too simple to uphold those interests effectively.
