If you are looking for a clear-sighted, universalist, internationalist, Marxian perspective on the Palestine/Israel-conflict (and read German), I really recommend this long piece by Walter Hanser [pseudonym for Gerhard Hanloser]: https://kosmoprolet.org/de/israel-palaestina-und-der-universalismus "Israel, Palästina und der Universalismus", published in Kosmoprolet #4 (2015).
I also can recommend this long piece on the historical relation between Marxism and Zionism, written from an anti-nationalist (maybe "ultra-left") perspective, ending with 197 footnotes to relevant sources: https://mcmxix.org/2018/07/09/zionism-and-marxism/
