I do not believe that to be the case. The lid was lifted (by us and others) when the brutal leaders were removed (or their power base weakened) who were able to keep a lid on these islamist loons.
I doubt these weirdo's give a toss what the likes of Sour Mash, you or I think. They would kill us all (and those who campaign for their liberty to do this) if they could in the name of their medieval version of islam
now it is free for all. We are very much winning the fight to wipe out ISIS over in the Middle East but Europe's bizarre anyone can come over policy means many of these loons are free to do wander around much of the continent.
However, we are winning. The prevent strategy among others along with our excellent (albeit stretched) security services are picking off these loons who want to kill us all for not believing in their warped version of Islam.
as people return to Syria (and we should encourage them to do so), focus will switch to North Africa and the mess continues
