DEAD SEA, Jordan – US Secretary of State John Kerry unveiled on Sunday a $4 billion economic plan to revitalize the Palestinian economy, as he called on Israelis and Palestinians to forgive past wrongs and return to the negotiating table. “The plan for the Palestinian economy is bigger and bolder and more ambitious than anything proposed since Oslo more than 20 years ago,” said Kerry as he spoke at the closing session of the World Economic Forum by the Dead Sea in Jordan.
