I found this under a Y-Net article about how boycotting certain Jews is a good idea, by Ziv Lenchner entitled, The show must not go on.
35. The green line has no legal basis in international law
The Jordanian-Israeli Armistice agreement is very clear that the Green line will not change any legality of the land. Read the document. The fact is that whether fair or not there is no document in international law which gives the Palestinians as a nation the rights to the land. More than that According to the Geneva Convention land can only be occupied territory if it was taken from one higher-contracting party with a legal claim to it by another higher-contracting party. Since it was taken from Jordan who had no legal claim and the Palestinians are not a higher-contracting party, the land is disputed. The Mandate for Palestine gave Jews the right to live anywhere in W.Palestine. Lastly the Palestinians had most Autonomy of their cities and towns in 2000. Arafat refused to negotiate and decided to go on a suicide bombing campaign instead. Is there any other country in the world which would be willing to give up part of its country to a group whose sole reason for existence as a nation according to the PLO Charter 1964 was to destroy Israel and specifically NOT TO CREATE A STATE. If anyone can find a peaceful part of Palestinians society go ahead. Otherwise don't blame Israel or ask of it something you wouldn't do yourself.
Jerusalemite (09.22.13)There are two further things that need to be emphasized.
The first is that demanding that Jews either move out of Judea and Samaria or stop building housing for themselves there is racist. It is racist on its face and we need stop justifying anti-Jewish Arab racism by agreeing with them that any future State of Palestine must be Judenrein, because when we oppose and demonize the "settlers" that is precisely what we are doing. We are sanctifying racism toward, and the ethnic cleansing of, our brothers and sisters in that part of the world.
The second thing that needs to be emphasized is that the demand to end settlement activity is what Abbas uses as an excuse not to negotiate a real peace and thus bolstering that demand hobbles any possibilities in a negotiated conclusion of hostilities. Well-meaning diaspora Jews who oppose the settlers and the settlements believe that they are an obstacle to a two-state solution, but that is only true if one agrees that Arab racism against Jews is justified.
