Thank you for recognizing that this stuff is not going on for a century or two, not even for centuries, but for millenia. The conflicts in the mesopotamian area are probably the oldest in the world. Reducing it to what happened after or shortly before WWII is like telling the history of the world/the universe starting from when homo sapiens came into place.

Trying to figure out who this land belongs to seems futile. How many great grandfather generations do you have to go back to make this part of soil "yours"? Is 10 enough? 15? 20? Imagine your family lived in this part of the region since 1000 AD just for someone to come and say they've been here since 900 AD so you are technically a foreign invader and don't belong there. Give back your house.

I sometimes wonder if they go back further than the religions the conflict is supposedly based on. I mean, tribal conflicts have always been a thing, right?
