"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."
Israel is already engaging in A, B, and C. So it’s not a matter of telling them to not do something they are currently not doing.
The problem with that reading is we already know Israel is on the wrong side of the genocide convention (bolding mine):
