@cicerone imposter,
Current ethics and humanity are the issues; not what happened before the current status of countries that have changed their borders through wars.
------------------------------------------------------------------
Current ethics and humanity as declared by you or anyone else have zero ability to change the fact that Israel have the land and the arm abilities and will to keep that land.
Countries and peoples had always changes their borders by wars and that little fact had not change one little bit and is unlikely to change anytime soon as in the next thousand years or so.
Would you like to point out the arm forces that is able and willing to engage the Israel and force your idea of morals on them?
The Pals claims to the land in question is as dead as the Indians claims to the Easthern Seaboard and for the same reason.
If England had not been able and willing to used arm force to keep the Falkland islands all the crying of the people then living on that island would not change their land from then belonging to Argentine.
I would suggest you grow up and view the world as it is not as how you would wish it to be.
