Hamas Leader Plays Final Hand: Trying to Lift Group’s Pariah Status It’s one of the greatest pressures the people of Gaza feel." Doggedness comes with a price, and Mr. Meshal is trying to balance that toughness with the need to open up, in a reflection of the shifting political landscape — and just maybe tilt toward more expansive politics that might one day bring Hamas out of the cold. Mr. Meshal, who spent his career shifting from one Arab capital to another, had his own close scrape: In 1997, a year after he became the leader of Hamas, Israeli spies sprayed poison into his ear on a street in Jordan, sending Mr. Meshal into a coma and setting off an angry diplomatic showdown between Jordan and Israel that ended with the delivery of a lifesaving antidote. He said the document — the product of four years of dialogue among leaders in Gaza, in prison and in exile — at the very least showed that Hamas was open to changing its ideas. "On one hand, they are attempting to appeal to hard-liners by not giving up their core principles,’’ said Mr. Thrall, the author of a forthcoming book on the Israeli-Palestinian conflict, "The Only Language They Understand.’’ "On the other, people like Meshal were hoping the document could lead to openings with Sunni Arab states and the West. Meshal said that We are making it clear that ours is a liberation project — not about religion or the Jews, The favorites to succeed Mr. Meshal are Ismail Haniya, a Hamas leader in Gaza, and Abu Marzouk, who is said to be living in exile in Cairo.
