All it takes is an intelligent reader to understand it. Mr. Haniyah wants all land captured in '67 returned, Jerusalem re-partitioned, and the 1948 refugees and their descendants returned to their land in Israel (or - perhaps - very handsomely compensated).
Since when is a state which wins a war expected to return its conquests to the losers? Since when do those expelled losers have the right to return and claim "their" lands?
Read the document with reasonable care and Mr. Haniyah is saying that Hamas wants the destruction of Israel as the price of peace. He's also saying that the Palestinians are at war with Israel...so who gives a shit what happens to them?
It's important to remember what Jabotinsky said 75 years ago - there's no right and wrong here, the Jews want a state of their own in their ancient homeland but the Palestinians, who've thought of that land as a home for a thousand years, don't want to let them have it.
It's important to remember that Arabs did not begin to call themselves "Palestinians" until after 1948. The "Palestine Liberation Organization" was established in 1964--before the so-called occupation of the West Bank and Gaza.
It's important to remember that the Paleoswineans always trot out this same old "retreat to the pre-1967 lines and give us a 'Right of Return'" when they are getting their butts whipped.
