Again, I know very little on the subject. But isn't a formal declartion by an establised country kinda how most states come to existence, I mean...in a formal way in the eyes of the established global community.
I really don't know much sorry.
But while we're talking about "rights" how are you defining that? Like a legal right or a moral one? I just ask because I remember the Romans were essentially the ones who forced most of the jews out of palestine in the first place. Then subsequent changes of the country heavily invovled violence and upheavels?
Given the history of the area, would superior force = rights?
just very briefly, and i will get to more later, but the british government had more right to dictate the course of her american colonies than it did to dictate the course of the palestinian people.
the most simple irish bogtrotter has a better grasp if british language and law than the most learned jurists in the world. experience may be the best teacher, but it is oft a cruel teacher.
a "national home" is not a "state."

and that is just for starters. as for this "right to exist", i am beginning to think it means nothing at all. no state has a right to exist. it just exists. it is moot. the mere fact that the palestinians are willing to sit down and negotiate with israel makes the recognition of israel's right to exist implicit. furthermore, that recognition has been expressed in very explicit ways many times, the most notable being the arab peace initiative.
