First of all, i just saw this meme, if i saw it before, i would have responded much earlier. Also, second, it was never their land, after the exile of Jews in that land by the Roman empire, it became a land predominantly Christian, the only times Arabs came to this land was the first Caliphate, which even then, they never called that land Palestine, The name Palestine came from the Romans, they took a Greek term, which meant connecting, and they called it Palestine. It was never an Arab name. And it never became a country until 1948, were both were given independence, and anyone with brains knows what happened next. And yes, you are right that Hitler wanted to rule more than Europe, but for that time, they had to stick with Europe. And fun fact: Hitler allied with the the Palestinian identity.
So it is you who dont understand what this conflict it, your not winning an argument, when i studied the conflict for years.
