Can anyone think of a solution to IS recruitment in this country?
Yep, you cut the limbs off the beast. The problem is that if you attempt to do that, there will be a series of "terrorist attacks" in Britain to try and stop you.
Look at what has happened today. We've seen an "Islamist terror attack" in Brussels, the heart of the EU, only a few days after a tentative EU deal with Turkey to arrest migrant flows into Europe in return for visa-free travel for certain categories of Turkish citizenry. Interestingly, Turkey was hit last Saturday by the same "terrorist" grouping in Istanbul.
Indeed, one of the most interesting things about "Islamist terror attacks" are when they occur and when they don't. Another very interesting thing to consider is not who the victims are, but who they aren't. And then there are the methods employed: to be blunt, suicide bombings have certain tactical advantages.
It all adds together to support the substantial body of evidence that indicates "Islamist terrorists" are proxy forces employed by certain wealthy, but low population, countries or ruling parties within those countries in order to advance their geo-strategic goals.
It's also pretty clear that the vast majority of the Muslim population in the West does not realise this could be the case. But that is hardly surprising, as the way it has been done is very clever. Through the subtle subversion of a religion, stupid domestic policies on the part of many countries in the world, and constant propaganda messages of victimhood shrouded in a pseudo-religious garb, agents of these "proxy force" countries have not only managed to create a self-recruiting movement across the globe that acts, essentially, as a fifth column, but they have also created the conditions by which the people around these recruited individuals no longer have the psychological clarity to pose certain questions, nor can they perceive that something really rather alarming is going on.
Indeed, these agents have been so successful in their efforts, they even have globally-privileged idiots traveling thousands of miles to clean toilets and provide cannon fodder, and they pay them less than they had to twenty years ago.
