The settlements are illegal according to international law for they violate the 4th Geneva convention, ratified by Israel. The West Bank continues to be occupied by Israel to this day.Your reference to Article 80 is interesting. Palestine is not still held under the Palestine Mandate (otherwise know as the British Mandate for Palestine, note British). 1B does not apply and nor 1c. What does apply Joseph E is the 4th Geneva convention, article 49, which says clearly that, quote 'The Occupying Power shall not deport or transfer parts of its own civilian population into the territory it occupies.' Your references to ICJ decisions are also strange. The first deals with African states, the second regards the Mandate, which says two states must exist, Israeli and Arab (very diffficult when Israel builds in the Arab section), the 3rd regards the wall, which in the advisory opinion was found to be contrary to international law, 14 votes to 1.
