The realization of world peace may also make the idea of individual nations obsolete. Some historians identify a long-term trend where nation-states stop fighting and become united. For example, old Europe with wars culminating in World War I and World War II, compared with the European Union; warring Chinese states compared with the modern Chinese nation. Some historians theorize that the world will eventually follow this pattern as well.
Dr. Frank C. Laubach, an American Missionary to the Phllipines in 1935 saw poverty, injustice and illiteracy as impediments to world peace. He developed the "Each One Teach One" literacy program which taught about 60 million people to read in their own language.
