the worst own goal came in 1997, during Binyamin Netanyahu's first term as prime minister. Mossad agents tried but failed to assassinate Khaled Mash'al – the same Hamas leader who is now warning of retaliation for Mabhouh's murder – by injecting poison into his ear in Amman, Jordan. Using forged Canadian passports, they fled to the Israeli embassy, triggering outrage and a huge diplomatic crisis with Jordan. Danny Yatom, the then Mossad chief, was forced to quit. Ephraim Halevy, a quietly spoken former Londoner, was brought back from retirement to clear up the mess.
