because one group is a terrorist group with "kill all jews" in their official charter, plus they aren't a country
palestine is a terrorist group with historical rights to the land and got forgeted over by the brits, and have been forced to live in the barren wasteland of the gaza strip oppressed by the rest of the world and constantly discluded from anything that could possibly benefit them and end the conflict they want to end. in desperate times people do desperate things, so they went terrorist mode---yet they're so loving poor that they can't really do any harm to anyone and just get the stuff kicked out of them by israelites. they aren't physically capable of growing and improving as a people since the rest of the world has them embargoed and is sending no aid
israel is a corrupt powerhouse of the world with their only rights to the land being religious and thus subjective. jerusalem got fought over too many times so britain carelessly just decided that israel should get the land because they're easier to cooperate with
since the conflict between israel and palestine has ended loving up both states, the only real decisions are to either wipe out both nations or to split jerusalem between the two of them---which should be done carefully and over time. Annoying Orange declaring out of the blue without seeming to give a damn about the historical context that jerusalem is the capital of israel alone sparked so much unnecessary and horrible conflict that
will solve absolutely nothing, and just escalate the problem. sudden one-sided support is literally just supporting israel bullying palestine then publicizing it as the horrible palestinians slaughtering their men so they can gain more support
if you fail to see the irony in germany not supporting a fully-Israeli Jerusalem you might just be legitimately autistic
east/west berlin was a completely different situation than what could be done with israel and palestine
