There is a path to coexistence, but it needs to overcome a lot of malevolence present on the side of Arab nationalism and political Islam. Currently, violent extremists are setting the tone when it comes to public opinion, and the governements are somewhere in the middle between turning a blind eye and qctively promoting the hate. The right-wing hardliners in Israel also promote a similar dynamic, they are strongly opposed by the state establishment and most of the public, but it seems like the extremists on both sides make each other stronger while dragging the two nations to hell. Yet, the kind of black and white thinking the villifies Israel and naively promote appeasement and pacifism with genocidial terrorists could only lead to a hugh storm of violence and suffering, that may or may not end with the destruction of Israel in the most violent way possible.

Egypt had 66,000 Jews before 1948. A peace agreement was reached in 1979. Yet almost none came back to live in Egypt. Jews and Israelis were very afraid to live in Egypt after the peace.

Only in recent years A-Sisi started to do some work to replenish synagogoues and care for the country's very long Jewish legacy, probably as part of his policy against extremism.

A Two-State solution could work in some constellation. a one state solution I see as leading to massacre and banishment of most of the Jews in the land.
