I’m squarely Pro-Palestinian in this conflict, but I will say it: what you’re saying is bullshit.
Israel should exist.
If not due to the fact that Jews in Palestine existed before Zionism and have a right just as much as other Palestinians to want a country.
If not due to the fact that some 60% of Israelis are Mizrahis, i.e., Arab Jews that were kicked out of virtually every other Arab country.
If not due to the fact that the Two State Solution, endorsed by basically the entire international community via the UN (resolution 242), means that …Israel should also exist.
If not due to any of those things… simply because 75 years after the founding of Israel, an Israeli nation exists. Entire generations of people have been raised with this self identity. They have the right to exist.
There is no putting the genie back in the bottle. Israel exists, and the Israeli people exists as an entity not exactly the same as the Jewish people. The debate about Israel’s existence is a waste of time and it does a disservice to the Palestinian cause.
