Jimmy and Rosalynn Carter were in the mood for a celebration of another kind, so they threw a birthday party for the Friendship Force, the international person-to-person exchange program they helped to launch from the White House 10 years ago. After Sunday services at their Plains, Ga., church, the Carters and about 30 Friendship Force members gathered for cake and remembrances. “An exchange is the best way to have world peace,” the former President said. The private, nonprofit Friendship Force, based in Atlanta, arranges visits between citizens of the United States and those of other countries. “I think the Friendship Force is really something to celebrate,” Mrs. Carter said. The program has grown to include participants in 42 states and 40 foreign countries, she said.
