In the West Bank it's plausible that Netanyahu plans to expand Israel's borders, but Gaza is quite tiny and heavily populated. Terrible though 34,000 Gazans killed is, that's only 1.5% of the population. If Israelis are going to live safely on that once-Palestinian land, they'll have to repeat the killing 70 times over.
Or maybe the plan is to make life so horrible for people in Gaza, that other Western nations have to take them as refugees. Well Turkey might, but after decades of being oppressed and after being raised to hate Israel, these would be very dangerous refugees for a European nation or the US to accept. They probably hate us too, so we'd have to go to extraordinary lengths to welcome and integrate them ... if they even consented to come.
So what is Netanyahu's long term plan for Gaza? Frankly I don't think he has one. He's clinging to power as a "war Prime Minister" as dissent over the conduct of the war grows, and he doesn't care that there will be an insoluble conflict for his successor to try to fix.
By the way, why do you call Netanyahu "Mileikowsky"? His name Netanyahu is from birth. It was his father's name, and his mother's name was Segal.
