The Israeli goverment needs to be voted out. I hope the Jews aren't building with expensive materials, because the government bulldozes it, over and over. There has to be a way to damage the tires on the bulldozers without getting caught. However, I don't think it's a good idea for the settlers to shoot at the tires, they might kill a soldier by accident.
If the soldiers come in on horses to trample the Jews, then it's fair to break a leg of the horse with a heavy pipe, to protect yourself.
