There is literally nothing Israel can do to appease them, other than its own self-destruction. What do you suggest?
What's happening is not merely a war over stolen land.
The Israel state has been terrorizing and oppressing the people of Palestine for decades. It IS almost impossible to appease the land which they brought war and brutality to, but a good start would be for the military to cease their savagery.
The only stolen land is that stolen by the arab muslims.
The arab muslims have been terrorising the Jews for the last 1400 years, starting with the genocides in Mecca and Medina. It has always been the arab muslims bringing war and brutallity. So stopping that would be a good start as shown by the peace treaties with Jordan and Egypt
