Palestinians share one common experience with North and South American Native Indians, with Australian Aborigines, and with New Zealand Ma'oris. They all have been subjected to settler colonialism.
Settler colonialism, usually technologically and militarily more advanced, is based on the erasure of already existent people, their culture and their memory, and substituting it with new foreign national entity that builds new culture, new history and new memory. To do this, settler colonialists have to get rid of the native people, their physical evidence, their history and their memory. They have to wipe off their existence from the world collective memory.
