I don't think it's a simplistic view at all, do you honestly believe that IS wouldn't have taken over in Syria if we had helped get rid of Assad? Our intervention over the last twenty five years has singularly been the main reason for the rise of these groups! First we removed the ultimately abhorrent leaders (Saddam and Gadaffi) that whilst unpalatable to the West kept these groups in check. Leaving these countries with puppet, weak leadership has allowed them to flourish. Not only that but we conveniently left a heap of high tech military hardware behind lol.
So now we have a whole generation of well armed, peed off muslims with nobody keeping them in check.
Turkey are far too strong, Iran, Saudi etc also. These countries should be sorting it out not us.
