Clearing out Qadaffi opened Libya up to islamist militants. Qadaffi kept a rein on the Brotherhood, interesting that some of the worst jihadis in the UK ( Manchester bombers) were from Libyan families that fled Qadaffi...because he wasnt an islamic hardliner, Same I expect with too many of the Syrian refugees..fleeing Assad because his govt is too secular. Thats where Europe gets its ISIS and al Qaeda refugees,
I think many of the Idlib refugees are professional terrorists working for Turkey, and are quite willing to earn their checks in Libya.
