Food for Peace is the primary tool by which the United States fights global hunger.See below President Dwight Eisenhower proclaiming the Food for Peace program (originally titled Public Law 480 in 1954)
The U.S. Food for Peace program opened the door to an international version, The United Nations World Food Program. Listen to President John F. Kennedy announce the creation of the UN World Food Program
Now today the two programs, U.S. Food for Peace and the UN World Food Program work together to fight global hunger.
See an example here where U.S. Food for Peace made donations to the UN World Food Program
