I have no idea what he remembers or has forgotten, but my intention was certainly not to raise the dubious spectre of a history discussion with one who begins with the yelp of a ten year old's "they started it!", as I do not consider that to be an intelligent start to any discussion.
My intention in utilising that quote was in order to demonstrate that disagreements do exist within the leadership of Hamas and that the opportunity for dialogue would and does exist if everyone would stop shooting one another and pointing fingers, and simply decide that peace, rather than ego, a distorted sense of "history" and a bloodlust for revenge is a viable and desirable conclusion to the mess that is going on right now.
There has to be an understanding that BOTH sides have a right to defend themselves and not only one side. Anyone who believes that the firing of rockets into (for the vast part) empty streets and fields somehow justifies the "self-defense" indiscriminate killing of civilians is the one being truly disingenuous (which was the word you actually wanted to use, by the way).
It is not my intention either, however, to have that discussion, as that is not the topic of the thread.
To specifically address what you have said, however, if you read the quote fully, you would have seen that he was quite specific about what he regarded as the "Occupied Territories", ie: Gaza, the West Bank and East Jerusalem. As has already previously been stated, there is a large contingent within the Hamas leadership which has been more than willing to discuss withdrawal to the pre-1967 borders. I am not surprised and really couldn't care less that there are so many Americans who a) choose to ignore this fact, b) have no understanding whatsoever of the actual history of the region and c) blindly and blithely wander about spewing radical Zionist propaganda as fact. Most Americans really have nothing to do with the actual process and serve only to annoy one another with arguments over the issues without actually understanding them.
What disturbs me is when the actual principles in what is supposed to be a peace process are guilty of the same things. This is extremely unhelpful, and will simply serve to extend the dispute further.
As far as "leaving Israel with undefendable borders", who is really being disingenuous now?
