You don't understand the issue. There will be new conflicts arise continuously, It's just what people in that part of the world do. You are thinking of the Isreal -Palestinian conflict. Don't forget Isreal-Egypt, Isreal-Lebanon, Iraq-Iran, Iraq versus the Kurds Arab-Isreal, Lebanese CIvil war, and many many more
They all like to fight and kill each other, different actors, same results. Neverending war.
There are things the rest of the world can do something about, and things they can't, Sadly, the rest of the world has not known how to tell the difference.
It's a shame and a travesty. But it's just how things are. There will not be peace in that part of the world, and there never will be.
Yeah, its a pity there can never be peace in the region:
