Libya faces along to the Mediterranean and had been effectively the cork in the bottle of Africa. So all problems, economic problems and civil war in Africa - previously people fleeing those problems didn't end up in Europe because Libya policed the Mediterranean. That was said explicitly at the time, back in early 2011 by Gaddafi: 'What do these Europeans think they're doing, trying to bomb and destroy the Libyan State? There's going to be floods of migrants out of Africa and jihadists into Europe', and this is exactly what happened.
