> Israel exists because Jews were prosecuted.
Israel exists because the West wanted a seat of military power in the Middle East. Just like America exists because various European powers wanted to exploit the Americas, until American leadership wanted to stop cutting them a slice. Just like Peurto Rico is directly under America's authority yet remains entirely unrepresented in it's government. Colonies all, of various justifications.
We exist in a world built by colonialism, by exploitation, who's foundations are lousy with the bones of cultures we dominated, some to extinction.
The idea that Jews needed a nation of their own after the Holocaust was debated at the time and remains so to this day, especially since the nation that was created is now engaged in it's own genocide. However there was no reason at all Israel HAD to be in the Middle East, apart from the fact that none of the colonial powers that worked to create it felt the urge to carve away their own land from themselves, and felt quite comfortable taking it from a bunch of nations who had zero say in the process.
I don't know if a Jewish state was needed or not, I'm not educated enough on the subject to have an opinion, but I know it was far from a consensus, and irrespective of how you want to slice that particular issue, the fact remains the powers that be at the time who were responsible for Israel's creation did not do it on land that was there's to give, but instead on other's. And said other's have had pretty understandable tension with Israel ever since.
