The various arguments being made to attempt to justify further Israeli settlement of the West Bank and Jerusalem are bizarre. Apart from appeals to biblical stories or some mythologized history well beyond the extent of actual, historical Jewish Kingdoms, which were extant for maybe 200 years out of the last 4,000-- they usually amount to deflection-- arguing that Israel isn't as bad as some other cess-pool or another-- and the accusation of support for terrorism, anti-Semitism, "Jew hatred", and the extermination of the Jewish people. 

Give it a break.

It's all about the occupation. Fix that,and you have a chance of peace and normal relations. If Israel continues on its current path, even if it were to settle all of Palestine, it would never be viewed as legitimate in the eyes of the world. That is one of the most important effects of the Dec 23 UN resolution.
