Final answer:
Jimmy Carter's foreign policy was defined by a commitment to moral principles, human rights, and peace, exemplified by the Camp David Accords between Israel and Egypt. After his presidency, Carter remained active in informal diplomacy and human rights work. Despite domestic and international challenges during his term, he is highly regarded for his post-presidential achievements.
Step-by-step explanation:
The centerpiece of Jimmy Carter's foreign policy during his presidency was his commitment to moral values, with a significant focus on peace and human rights. Carter's approach led to improved relations with China, the discontinuation of military support to the Nicaraguan dictator Anastasio Somoza, the return of control over the Panama Canal to Panama in 1999 and engagement with the Soviet Union through the SALT II talks. However, the most notable accomplishment was his role in brokering the Camp David Accords between Israel and Egypt, which eventually resulted in a peace treaty between the two nations in 1979.
Even after his presidency, Carter continued his efforts in promoting peace and human rights through informal diplomacy, as demonstrated by his visit to a referendum polling center in Sudan in 2011 with the Carter Center. The resolution of the Israeli-Palestinian conflict and the energy crisis were dominant issues during his term, which subjected every action he took concerning the Middle East to intense scrutiny both domestically and internationally.
In the aftermath of his presidency, those who study Carter's legacy acknowledge that his reputation as president was overshadowed by economic and international turmoil, leading to his defeat by Ronald Reagan. Despite mixed views on his presidency, Carter is widely respected for his post-presidential work in various causes, cementing his status as a highly successful former president in the area of informal diplomacy and conflict resolution.
