Step-by-step explanation:
During his presidency, Jimmy Carter played a key role in helping Egypt and Israel work toward peace. In 1978, he brought Egyptian President Anwar Sadat and Israeli Prime Minister Menachem Begin to the Camp David retreat in Maryland for negotiations.
This led to the signing of the Camp David Accords, a historic peace agreement between Egypt and Israel. As part of the agreement, Israel agreed to return the Sinai Peninsula to Egypt, and Egypt became the first Arab nation to officially recognize Israel. Carter's efforts in mediating the peace negotiations were highly regarded, and he was awarded the Nobel Peace Prize for his role in promoting peace in the Middle East.
