Without these cultural and religious layers, what remains is same for everyone. A human body.
But that also means Jews/Christians have a very rocky road together. Technically, "Christians" performed the Holocaust, for starters.
It begs a question - when you add in Islam, why do Christians and Jews suddenly become political allies?
It's important to note that we throw around terms like The Muslims as though all Muslims and Christians, etc have the same beliefs and agenda, and that's clearly not the case.
The subject is completely invisible to us except when we discuss interesting parts of the religions we believe.
I for one believe that religion is an ethics and conscience system, and when practiced correctly, all of them points to the same direction, albeit with different narratives and paths.
Goes back to the Crusades, the Islamic invasion of Europe and the fall of Constantinople
It’s not like Christianity embraced Jews either, but they did not present an existential threat
What's really infinitely more likely is that israel and usa share some common enemies, and usa doesn't really have all that many geopolitical allies in the region to chose from. I don't know why everyone reaches for weird religious conspiracies when the obvious geopolitical explanation will do.
