People from that place will never stop fighting. If it's not with people of different religion, then different skin color, or different street that they live in.
I think it's the air or water they drink.

From ancient empires, kingdoms, clans, factions, religions, to generations into the future, they will not stop fighting.

Copilot:
After these many killings, conquer, wars, no one is innocent anymore. There are no righteous faction anymore.
Just like how Chinese are taught to hate Japanese in China, their younger generation will have no choice but to hate each other forever.
Even if they kill off the whole Israelis control region and won, the people living on the north part of the street will fight with people living in the south part of the same street because of some stupid reason.

Don't choose sides. Live your own peaceful life, be prosperous, be well, be kind, be generous, be educated, and conquer them with how good your life can be by not fighting wars.
