Israel and its settler garrison are carrying out the standard colonialist formula throughout history (epitomized by the US model in its conquest) : eviction and genocide of the indigenous inhabitants, and theft of their lands.
This is defended under many premises, a "religious" calling, a "civilizing" venture (with orientalist undertones), and many others, but the goal is the same as all imperialist ventures: theft of land, labor, and natural resources. People from around the world, no matter how rich or poor, are invited to join in this colonial project, and many do, because of the promise of cheap land.
Predictably, Israel calls anyone who opposes this genocide as "terrorists", even though by all reasonable definition of terrorism, its the settler garrison who are the real terrorists: murdering innocent civilians, stealing their towns, and erasing the old names. In Palestine, the largest of this event was called the Nakba, whereas in the US, the entire 1800s was a westward-expanding colonial war defeating hundreds of native tribes and killing anyone who resisted.
The US is the primary supporter of this project, because Israel is for them, a giant, unsinkable aircraft carrier / military base in the middle east, which can be used to project western military power on the resource-rich middle east. As Joe Biden said: "If Israel didn't exist, it would be necessary for the US to invent one herself."
I suggest watching this video, as its the best short introduction: How Palestine became Colonized.
