Hardly just my interpretation.

"The right of the Jewish people to the land of Israel is eternal and indisputable" says the English version of the Likud Party's original platform.  That has nothing to do with 1922, which created no binding rights.  The 'land of Israel' refered to is Eretz Israel - the land god gave to the jews.

Not all Likud members still believe it, but cabinet minister Ofir Akunis is one who does.
