I don't think they can do complete u turns on everything they claimed a short while ago.

Israel will exist and will continue to exist until Islam will obliterate it, just as it obliterated others before it" (The Martyr, Imam Hassan al-Banna, of blessed memory).
The Islamic Resistance Movement believes that the land of Palestine is an Islamic Waqf consecrated for future Moslem generations until Judgement Day. It, or any part of it, should not be squandered: it, or any part of it, should not be given up. Neither a single Arab country nor all Arab countries, neither any king or president, nor all the kings and presidents, neither any organization nor all of them, be they Palestinian or Arab, possess the right to do that.
There is no solution for the Palestinian question except through Jihad. Initiatives, proposals and international conferences are all a waste of time and vain endeavors.

Forget all of the above, we have changed our minds, especially the bits in bold.
Oh, the "new" one also clarifies "from the river to the sea" statement. It is the whole of Israel.
The Land of Palestine:
2. Palestine, which extends from the River Jordan in the east to the Mediterranean in the west and from Ras Al-Naqurah in the north to Umm Al-Rashrash in the south, is an integral territorial unit. It is the land and the home of the Palestinian people. The expulsion and banishment of the Palestinian people from their land and the establishment of the Zionist entity therein do not annul the right of the Palestinian people to their entire land and do not entrench any rights therein for the usurping Zionist entity.
The Palestinian Political System:
27. A real state of Palestine is a state that has been liberated. There is no alternative to a fully sovereign Palestinian State on the entire national Palestinian soil, with Jerusalem as its capital.
