- Egypt could to suspend a key peace treaty if Israel pushes into Gaza’s Rafah: officials
- Here’s a look at the history of the 1979 treaty and what could happen if it is nullified

It was a warm handshake between the unlikeliest of statesmen, conducted under the beaming gaze of President Jimmy Carter.
Sunlight streamed through the trees at Camp David, Maryland, as Egyptian President Anwar Sadat and Israeli Prime Minister Menachem Begin solidified a landmark agreement that has allowed over 40 years of peace between Israel and Egypt. It has served as an important source of stability in a volatile region.
That peace has held through two Palestinian uprisings and a series of wars between Israel and Hamas.
But now, with Prime Minister Benjamin Netanyahu vowing to send Israeli troops into Rafah, a city in Gaza on the border with Egypt, the Egyptian government is threatening to void the agreement.

How did the treaty originate?
It was 1977, and Begin, Israel’s new prime minister, opposed ceding any of the land Israel had conquered a decade earlier in the 1967 Mideast war. Those lands included Egypt’s Sinai Peninsula.
