To be honest, countries don't have right to exists countries don't have rights. Rights are inneherently for humans. It's a stupid notion, countries are established by violence and their borders are enforced through violence, it means that Israel or any country has the right to use violence against those whom they judge to threaten their existence. And that includes the population of said country, if the people of country A decides one day to become country B, they can't because country A has a right to exist but not the none-existing country B.
