Probably Netanyahu and his buddy Kushner have been salivating over Gaza's Mediterranean coastline, but building another playground for the uber wealthy means the right-wing settlers lined up to steal Gaza will not have as much property to take. And taking all the land is Israel's goal. Perhaps Huckabee let the cat out of the bag when he said that Israel has a right to take all of the Middle East. They certainly do not and couldn't do it anyway, but they have been carving out extra slices for decades.
I hate even to think this, but I believe the Palestinians will soon be a decimated population, either murdered by Israel or put on a ship and sent to poor countries in Africa that are paid to take them. Netanyahu has Trump under his thumb, and he will need to accomplish his goal of eliminating all Palestinians from Gaza and the West Bank before the end of Trump's term because another president (unless it's Vance) is unlikely to support his genocide. Trump may have no real goals for this war, but Netanyahu certainly does. Eliminating Iran eliminates the money for Hamas and any resistance to Israel's ongoing genocide of Palestinians.
Just my opinion, but Netanyahu is totally evil and a long-term strategist unlike Trump, who never thinks of consequences or strategy and is constantly looking for more ways to make money. Trump is perhaps his last opportunity to finally get rid of all Palestinians and fulfill his goal (and indeed that of the founders of Israel) of having all the land of Palestine.
