Anything less than the clearing of all traces of things Islamic in Gaza will perpetuate the problem.
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.
