One needs to understand that only Syria is in charge of Syria and Russia is a huge influence. When it comes to Gaza, there are 3 entities in charge: Israel, leadership in Gaza and Egypt. So just by mere definition, one would need to free gaza from 2 of the 3 entities so it can be definitively deemed free. To be quite fair, I can assure that Israel would have no issue leaving the situation as it is (the same cannot be said for the west bank). But I cannot assure you that Hamas and Egypt would leave the situation.
