to get the Arab League to enforce a demilitarized zone between Palestine and Israel
Let’s say that this is what he’s saying. I don’t see you mentioning what Israel has to do, so this reading cannot not be a solution cause it leaves out the responsibilities of Israel. What would you put on the top of the list of what Israel has to do? My answer to that would be that Israel has to stop bombing and starving, civilians and children, as well as recognize Palestine.
On Genocide, Israel is doing at least 3 of the 5 required for one to be called as such. And ICJ court said "plausible" so far.
In the present Convention, genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:
a. Killing members of the group;
b. Causing serious bodily or mental harm to members of the group;
c. Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;
d. Imposing measures intended to prevent births within the group;
e. Forcibly transferring children of the group to another group.
