Our relationship to the Egyptian government has long been an archetypal example of foreign policy realism in action, in the sense that we’ve consistently put our interest in having a cooperative and stable government in Cairo ahead of our commitment to democracy and human rights. Other, non-realpolitik-based approaches would have yielded a different strategy long ago: A principled non-interventionism would have rejected our patronage of the Egyptian military as a costly “entangling alliance” (as Rand Paul did even before recent events), and a principled Wilsonianism would have rejected it as a betrayal of American values. But American policymakers of both parties have stuck with realism instead, consistently choosing the devil we know over the risks inherent in cutting Egypt loose.
