Territory cannot be acquired by war , LBS, it's illegal. Therefore the only practical legal avenue is for both sides to accept the ruling of the UN.
It would be legal to change the UN borders by negotiation and agreement involving all parties, but that would require agreement by the majority of Palestinians, including the six million in the refugee diaspora.

Pigs on the wing.


Remember, no Palestinian leader can legally give away territory without the agreement of his people. Arafat tried that. A sneak 'agreement' with Abbas is going nowhere.
