That is a territorial/sovereignty claim (i.e., rejecting Palestinian sovereignty/statehood in that space). It is not an explicit call to kill, expel, or physically destroy Palestinians, nor does it literally say “for Jews only.”

Under the Genocide Convention, genocide requires specific intent (“intent to destroy, in whole or in part”) a protected group, plus one of the listed genocidal acts (killing; causing serious harm; inflicting conditions of life calculated to bring about physical destruction; preventing births; forcibly transferring children).
