40 years ago: Israel and Egypt establish diplomatic relations

On January 26, 1980, Israel and Egypt established diplomatic relations, exactly 10 months after the signing of the Egypt-Israel Peace Treaty in Washington, six months after the Camp David Accords were signed by Egyptian President Anwar Sadat and Israeli Prime Minister Menachem Begin.

It's interesting to note that Egypt isn't mentioned as one of the nations attacking Israel in Ezekiel 38--an attack which is yet in the future:

And the word of the Lord came unto me, saying,
Son of man, set thy face against Gog, the land of Magog, the chief prince of Meshech and Tubal, and prophesy against him,
And say, Thus saith the Lord God; Behold, I am against thee, O Gog, the chief prince of Meshech and Tubal:
And I will turn thee back, and put hooks into thy jaws, and I will bring thee forth, and all thine army, horses and horsemen, all of them clothed with all sorts of armour, even a great company with bucklers and shields, all of them handling swords:
Persia, Ethiopia, and Libya with them; all of them with shield and helmet:
Gomer, and all his bands; the house of Togarmah of the north quarters, and all his bands: and many people with thee. Ezekiel 38:1-6
