Israel claims to be threatened by its neighbors. Israel claims to want peace with countries in the region. Neighboring countries have repeatedly stated that a precondition to normalization is a just solution for Palestinians. But Israel does not want a just solution.
In other words, the problem is entirely self-inflicted. Israel wants peace, but without making any concessions on the issue of Palestine. So instead it pursues a system of “peace through violence” - just like it does in the West Bank and Gaza.
As for the peace treaties:
Jordan simply did not have the ability to fight Israel any longer, or to deal with Palestinian factions operating in its territory.
Egypt wanted its land back after failing to reclaim it in 1973.
Besides, Israel has since made peace with Egypt and Jordan.
Now, back to the present day. Palestinians live under a system of occupation and blockade and recently genocide. This is not a just situation. It is also not sustainable without continued repression and use of force. There is no way that Israel will be welcomed into the wider ME under this regime.
