There is no ethnic cleansing when that ethnic population in the area went from 500k to 5 million.
You say this ethnic cleansing started in the late 1800s? You are the one with a completely revisionist idea of history. When Jews immigrated to the area in the late 1800s they were first met with hostility towards them. Their land often pillaged by Arab marauders. All while they were starving and struggling to carry water on camel back to their settlement.
There was no settler colonialism in the late 1800s. Even the first wave of settlers faced hostility from the Palestine-Arabs.
They’ve made it their own prison even before they attempted to invade and destroy Israel on 1948.
