Oscar Arias Sanchez, former President of Costa Rica and Nobel Peace Prize laureate, exemplifies visionary leadership and peacemaking. He led Central America’s peace process in the 1980s, risking his career to champion reconciliation and regional stability. His courage to champion democracy, human rights, and disarmament reshaped his country and inspired global diplomacy. As an elder statesman and advocate for sustainable development, Arias reminds us that effective leadership combines moral conviction with strategic courage—and that one person can guide multiple nations toward peace.
