Israel a une vision stratégique réaliste.
 
A weak IS is, counterintuitively, preferable to a destroyed IS. IS is a magnet for radicalized Muslims in countries throughout the world.These volunteers are easier targets to identify, saving intelligence work
If IS is fully defeated, more of these people are likely to come home and cause trouble.
 

Furthermore, Hizballah – a radical Shiite anti-Western organization subservient to Iran – is being seriously taxed by the fight against IS, a state of affairs that suits Western interests. A Hizballah no longer involved in the Syrian civil war might engage once again in the taking of western hostages and other terrorist acts in Europe.
 
The Western distaste for IS brutality and immorality should not obfuscate strategic clarity. IS are truly bad guys, but few of their opponents are much better. Allowing bad guys to kill bad guys sounds very cynical, but it is useful and even moral to do so if it keeps the bad guys busy and less able to harm the good guys. The Hobbesian reality of the Middle East does not always present a neat moral choice.
