Now that Egypt has again replaced its leadership, what will it mean for Israel? The two neighboring countries fought three full scale wars until the 1978 Camp David Accords in which Israel relinquished control of the strategic and oil-rich Sinai Peninsula in exchange for a cessation of hostilities with its southern neighbor. The ouster of President Hosni Mubarak in 2011 resulted in an increased level of lawlessness and violence in the Sinai region. The repeated attacks on the natural gas pipelines that supplied power to Israel, Jordan and Egypt were one example of such anarchy. It remains to be seen how Wednesday night's military coup will affect the Jewish State.
