Israel is the closest ally of the US in the Middle East or in other words, they represents the US in the region. Whatever they do is under the direction and interests of the US.

Just think, a country becomes rich and powerful by selling weapons, looting resources, land...from the rest of the world. They then maintain their dominance by oppressing, suppressing, obstructing, and even attacking any nation that threatens their position. I would be surprised if what they want is "peace" because that would make them weaker. Instead, in order to sell more weapons, to have more mineral resources, they need to have war. That is why the world has never been peaceful since the United States became a superpower, especially in regions and countries with huge mineral resources.
