Scrapping around and doing nothing is no solution.The west wants to scrap around looking for reasons, trying to understand, looking at why we are to blame - what can we do that will make the next would be terrorist stop. But these terrorists simply don’t give any justification for their actions - nothing - if you catch them in one piece it’s usually to the sound of “allah is great” or something similar not “this for the 40 slaughtered at a wedding”. I think only ISIS have said they want the death of all infidels or something equally genocidal.
