Joseph Nye introduced the term "smart power" to refer to the skillful combination of hard power (military and economic might) and soft power (diplomatic and cultural influence) to achieve objectives. Smart power became a core principle of Obama's foreign policy approach. While smart power strategies can optimize national influence and security, instituting them faces obstacles in consistency with human psychology, high cognitive costs of complexity, and challenges operationalizing outcomes over resources for decision-makers. Ultimately, optimal strategies may be even smarter than smart ones.
