Since the days of Franklin Roosevelt, and the service and sacrifice of our grandparents and great-grandparents, our country has borne a special burden in global affairs. We have spilled American blood in many countries on multiple continents. We have spent our revenue to help others rebuild from rubble and develop their own economies. We have joined with others to develop an architecture of institutions -- from the United Nations to NATO to the World Bank -- that provide for the common security and prosperity of human beings.
