In his book "Overthrow: America's Century of Regime Change from Hawaii to Iraq," author Stephen Kinzer discusses the significant impact of John Foster Dulles on American foreign policy. Dulles was driven by two main passions throughout his life: a fervent opposition to Communism and a strong commitment to safeguard the interests of multinational corporations. His dual focus shaped many U.S. actions during the Cold War, with lasting implications for international relations and economic dynamics.

Kinzner's analysis highlights how Dulles’ ideologies influenced various regime changes and interventions worldwide. By aligning national interests with corporate ambitions, Dulles contributed to a foreign policy that often prioritized economic benefits over democratic principles, leaving a complex legacy that continues to resonate today. His actions reflect a broader trend in U.S. history where the fight against Communism was intertwined with corporate interests, demonstrating how economic motivations often overshadowed ethical considerations in foreign interventions.
