What happened in 1977?

Sponsored by Aish.com: In 1980, Israel and Egypt exchanged ambassadors, marking a new era of cordial, if cold, diplomacy. In 1973, Egyptian President Anwar Sadat had orchestrated an attack on Israel in the Yom Kippur War, but after suffering defeat he became resigned to Israel’s existence. In 1977, Sadat and Menachem Begin signed the Camp David Peace Agreement, for which they received the Nobel Peace Prize. Much of the Arab world was outraged by Sadat’s overtures toward Israel, and he was assassinated by a Muslim in 1981.
