I don’t know what this poster says as I don’t know Hebrew. I think it has to do with not forgetting your Jewish roots or something.

My opinion, for what it’s worth, is that both Israel and Palestine have a right to exist and both need to feel and actually be secure from/with each other. An independent Palestine must be created and then the world owes it to the Palestinians to pour money in to create a prosperous and stable nation that can co-exist with Israel. If they can basically resolve many of the ethnic and territorial disputes in the former Yugoslavia they can do it in Israel/Palestine/Jordan. Make it so.
