Obama and Hillary decided to kill Gaddafi (spell it however you like, you know who I mean) and in so doing they transformed Libya from a stable nation into a chaotic one that the terrorists quickly dominated. The downside of that (other than the obvious one - terrorists in charge) is that they threw open the ports and started flooding young muslim men into Europe. Hillary and Obama created the 'migrant crisis'.
So they decided to destroy Libya and they threw in destroying Europe for free.
