It was said of the Roman generalissimo Sulla that there was no better friend or worse enemy than he. This maxim of foreign policy––support and help your loyal allies, and damage and punish your enemies––was proven common sense for millennia. Then came the age of moralizing internationalism, the belief that a “new world order” had made that realist truth anachronistic and primitive, a reflection of our benighted past. Now diplomatic engagement, democracy promotion, foreign aid, and multinational institution see to global security, peace, and prosperity. As a result, today there is no worse friend, and no better enemy than the West’s foreign policy and national security agencies.
