Israel-Gaza exchange rocket and air strikes killing 10

[500]

Nice Logic-
Go beyond further that- and the land belonged to dinosaurs-

Thats your logic. You want to restore Arab khalifate from 1000 years ago. But why not other empires: Persian, Alexanders, Roman, Mongol, Otttoman, British?

Arabs have 13,159 thousand km2 today, the overwhelming majority of these lands are extremely poor and undeveloped. Maybe they should concentrate on these lands first, instead trying to capture and destroy 21 K from Israel?
