What happens when a government tries to force people off land they've been squatting on for decades? It depends. In England the squatters demonstrate but probably end up leaving, and no-one but the locals cares anyway. In Israel the squatters return again and again, backed by lots of outsiders who couldn't care what the law says, if it's Arabs they've got to be right and Israel has got to be wrong.
On a similar note, the French are deporting Gypsies (Roma) to Romania, even though both countries are in the EU so their citizens may live where they wish. In Israel such policies are cast as despicable.
