Since Reagan left office in 1989, substantial debate has occurred among scholars, historians, and the general public surrounding his legacy. Supporters have pointed to a more efficient and prosperous economy as a result of Reagan's economic policies, foreign policy triumphs including a peaceful end to the Cold War, and a restoration of American pride and morale. Proponents also argue Reagan restored faith in the American Dream after a decline in American confidence and self-respect under Jimmy Carter's perceived weak leadership, particularly during the Iran hostage crisis. Reagan remains an important symbol of American conservatism, much in the same way that Franklin Roosevelt continued to serve as a symbol of liberalism long after his own death.
