Political zionism is an ethnic cleansing ideology: maximum land, minimum indigenous (Palestinian Arab) inhabitants. This is a constant. Nothing has changed in 100 years. It explains, why Israel's army and political class (Labour, Likud and the rest minus a small minority of decent Israelis) stand by and do nothing, while colonists are actively driving Palestinians from their land. They are all involved and thus support the crime. So does the "international community", which is standing by and allows it to happen without taking action.
