It would have been really stupid for Israel to have given the oused, hated tyrant of Egypt a sactury. But the Muslim Brotherhood would have loved it. It would have become their rally cry "look the Isralie's are protecting our bloodsoaked dictator!" Also the military running Egypt would be pleased "We would love to try him in court, but oh, the Israeli's have him". Remember in Iran when the Shar was given refugee in America? And the Mullars used this to wip up anger and hate against the US? Leading to the US Embassy seige and them gaining power over the liberals and secular Irainians?
