If Palestinians cannot secure their own land, she said, “then you will never see a day of peace.”

One speaker likened “Zionist settlers on the West Bank” to Osama bin Laden, saying both had been “blinded by ideology.”

Obama adopted a different tone in his comments and called for finding common ground. But his presence at such events, as he worked to build a political base in Chicago, has led some Palestinian leaders to believe that he might deal differently with the Middle East than either of his opponents for the White House…
