It does not matter one shekel if the Knesset did or didn't endorse Geneva Convention 4, it governs all countries and all wars whether the participants buy into it or not. That is why the international community can repeatedly insist that ALL settlement building in occupied Palestine is illegal. It does not need the Knesset's consent. The fact that Israel has put in place a number of tricky pseudo-legal mechanisms to enable settlement building, like declaring land 'government' and 'public', taking land that has not been worked arably for a certain number of years (as many of the Pals are shepherds and the land is not arable, this is a blatent trick!), sequestering land for supposed military use that turns out to be 'surplus' and is promptly handed over to settlements or passed brazenly to the Nahal to start settlement groundwork - these are the kinds of faux-legal administrative tricks that the South Africans got up to in creating bantustans and the Nazis in sequestering land and businesses. There is no valid legal basis underpinning Israel's definition of 'public' land and 'legal' settlements, neither exist nor could exist for an occupying power. It is a grave mistake to give any credibility to the Israeli land-seizure process, it has none and will be blown out of the water when it finally gets before an international court, which day will undoubtedly come.
