Zionists invaded Palestine in 1947-48
Being deliberately ignorant of history isn't helping anyone.

I do not support the apartheid state of Israel or the illegal settlements and occupation of Palestine, but Jewish people belong on parts of that land just as much as Palestinians belong on others, and this conflict will never be resolved as long as people, especially those who brush of thousands of years of history aside as nuance because its easier than actually making an effort to understand it, argue that only one group has a rightful claim to the land.
An anarchist should be supporting the people, not one state or another, and this isn't to say that there is a power balance or that both sides are responsible, no, only Israel is, but those in power over both people are using them as pawns to stay in power. They are the ones who need to be removed.
