The Arab country to tried to achieve peace with Israel was Egypt. The Egyptian president Anwar Sadat signed a peace treaty with Israel. The international reaction was that of shock. Because Egypt became the first ever Arab country to sign a peace treaty with Israel that officially recognized it as a country. Because of this, Egypt temporary was suspended from the Arab League and Anwar was assassinated.
