Israel really gets off on playing a Billy the Kid role, swaggering round the M-E murdering opponents. Look how tough we are, says Billy, look how invincible we are, the audience howls in delight. Neither are true and these things do come back to haunt you. If you assassinate an enemy's leaders, they naturally respond in kind. The IRA alleged that the UK had a shoot-to-kill policy, then suddenly we were dragging PM Thatcher out of the rubble of the Grand Hotel bombing in Brighton. That is one reason states do not go in for extra-judicial killing of political opponents. Another is that it is physically impossible to provide close security for all the possible state targets of reprisal attacks, so do not provoke them. It is neither a very tough nor clever policy. Billy was not so tough really and Mossad is nothing special. When Hamas carries out the inevitable reprisal killing, the Major General will need to explain why his merry men provoked it and what Israel gained specifically.
