He contended that 'superior power gives no right, either moral or legal, to do with that power all that it is physically capable of doing' ## Morgenthau's view on power Morgenthau saw real power as influence through consent, not coercion. > Real power, Morgenthau insisted, lies in the ability to influence a country through consent, not coercion ## Morgenthau's final warning Morgenthau warned of American moral decline without purpose. > The United States has lost its purpose, and unless it rediscovers it, discrete foreign policy successes will be irrelevant ## Key takeaway Morgenthau's realism warns Trump's power overreach risks American moral collapse.
