Take the old man himself. From the start, the Israeli line was simple. Sheikh Yassin was the "head ofthe snake" - to use the words of the Israeli ambassador to London - the head of Hamas, "one of theworld's most dangerous terrorist organisations". But then came obfuscation from the world's media.Yassin, the BBC World Service Television told us at lunchtime, was originally freed by the Israelis in a"prisoner exchange". It sounded like one of those familiar swaps - a Palestinian released inexchange for captured Israeli soldiers. And then, later in the day, the BBC told us that he had been freed"following a deal brokered by King Hussain (of Jordan)". Which was all very strange. He was aprisoner of the Israelis. This "head of the snake" was in an Israeli prison. And then, bingo, thissupposed monster was let go because of a "deal". Sheikh Yassin was set free by no less than thatlaw-and-order right- wing Likudist Benjamin Netanyahu when he was Prime Minister of Israel. King Hussainwasn't a "broker" between two sides. Two Israeli Mossad secret agents had tried to murder a Hamasofficial in Amman, the capital of an Arab nation which had a full peace agreement with Israel. They hadinjected the Hamas man with poison and the late King Hussain called the US President in fury and threatened toput the captured Mossad men on trial if he wasn't given the antidote to the poison and if Yassin wasn'treleased.
