If to you legitimate for a country to set up a no-go zone in another country and kill anyone who enters it, I assume you agree Lebanon can kill Israeli soldiers coming too close to their border. If you feel it legitimate for Israel to kill Gazans setting up defensive mines near their border, I assume you agree Lebanon can kill Israelis planting mines along its border. Or is there one set of rules for Israel and another for everyone else?
