Mr. Meshal, one of the founders of Hamas, barely escaped assassination at the hands of Israeli agents in 1997 in Jordan. He was injected with a poison, but the agents were caught. King Hussein, furious that this was taking place in his country, obliged Israel to send an antidote. Mr. Meshal ultimately went to Damascus, the base for Hamas apart from its leaders inside Gaza. The Israeli prime minister during that assassination attempt was Benjamin Netanyahu, who has been returned to that post. Mr. Netanyahu has said that Hamas is a tool of Iran and that Iran is the biggest danger to world peace and must be stopped.
