"the land-grabbing and settlement building in the occupied territories by Israel is regarded as illegal by the United Nations and by international law."
I know the U.N. sometimes says otherwise, but a bit of fun can be had questioning U.N. officials and making them stutter about what exactly is in the law books. Sovereignty in the West Bank still rests upon the old British Mandate, which was set up to promote Palestine as the Jewish Homeland. Jewish settlements are legal as long as the traditional (Ottoman, that is) civil rights of the Arabs are respected.
Originally Arabs throughout the Middle East were supposed to respect the civil rights of Jews in return but Jordan ejected its Jews in 1920 and the other Arab states joined in oppressing or ejecting their Jews in the ensuing decades, as Britain cynically abused its Mandate to cut down the allotted territory and restrict Jewish immigration. It wasn't for nothing that many Jews seeking to escape Nazi Germany ended up in Shanghai, rather than Palestine.
