That won’t happen, because of Israel’s laws. Their own law protects all religions, Christianity, Judaism and Islam. Those laws also protect all religious sites. So there will be no clearing of Islam from Gaza. You’re simply engaging in a pipe-dream.
However, that’s not to say there won’t be a clearing of the “Islamic Terrorists” like Hamas from Gaza.
It is a pipe dream. Alas, pipe dreams contain the only real solutions. Politics renders reality as pipe dreams.
