The Camp David Accords, the Egypt–Israel Peace Treaty and the aftermath of relations between Israel and Egypt are considered a modern example of a cold peace. After having engaged each other in five prior wars, the populations had become weary of the loss of life, and the negotiation of the accords and the treaty were considered a high point of the Middle Eastern peace process. However, Egyptian popular support for the treaty plummeted after the 1981 assassination of Anwar Sadat and the 1982 Israeli invasion of Lebanon, and perception of the treaty has not recovered in the Egyptian populace ever since.
