Zionism is the idea of colonial occupation. The internal logic will always end in ethnic cleansing. It did in 1948. It's doing it now. American Manifest Destiny had a similar function, and it also resulted in massive genocide for which we have not atoned.
Zionism is done. A secular democratic state for all people with the right of return guaranteed for displaced Palestinians along with some kind of reeducation / denazification program for the genocidal citizens of the current state of Israel is the only viable solution.
As a Jew, I don't think Arabs should pay for Germany's crimes. I think Germany should pay. They paid a little already. They should pay more, especially now that they are supporting this genocide too.
