Historically: the jews were scattered after getting their shit slapped by the Assyrians. Israel will always be culturally significant to the jews
The other semites (Arabic people) also have cultural claim to Israel.
eg- The western wall, a famed jew sighting-ground, is also the same place the prophet and king shitskins Mohammed tied his very special mount, buraq, off to. Buraq was special because he
had the face of a beautiful woman and was made of fish and birds. Please do not confuse buraq with
May, who is also a horse woman who has the scent of a fish and makes us want to administer the bird.
They (and the Christians) have been fighting over who owns this chunk of dirt
Contemporarily:
The Arabs had been there for a long time and the allies won WWII and we put the Jews there because an Austrian man ran a strange series of bakeries in Germany.
The Arabs are mad about it. They fought this idea tooth and nail about 100 years ago.
The jews like this. Allies felt bad or some shit and decided to give them things like money, materiel, and a copy of "How to Win Friends and Influence People" as a Christmas gag gift. This was mostly because they don't celebrate Christmas, but they read the book and have manipulated the entire planet into believing in a concept called "asshole capitalism" (see the early 2000s housing crisis) which is also, for brevity, called "being a jew".
TL;DR
* everyone thinks they own it
* jews have better military assets and the West is still kind of butthurt at goatfuckers
* arabs are culturally murderous and don't really care who they kill so long as they belong to Team Bad
* religion is the reason fighting is happening
** and the West is kind of attachment-related
