This topic reminds me of the one under discussion back when I first stumbled on this site:

It is a very long thread, and the comments get a bit disorderly towards the end, but I was very struck by the idea that the Jihadis
would be completely unprepared for the eventual and, from their point of view, entirely unintended consequences of their actions,and that their boasting from the shadows would fade away as the shadows
finally closed around them.
What is happening to the Jihadis now may be due to a combination of many things, or of just a few, or perhaps there really is one “silver bullet” technology. Whatever, it certainly sounds like good news, though it has seemed to be a very long and bloody time coming.
