I don&#x27;t know about that. Or, in other words, it remains to be seen.  So far there have been thousands of Europeans or at least European residents who have been willing to travel thousands of miles to do battle (with pretty high odds of becoming casualties) so it&#x27;s not so much that they have not been &quot;brainwashed enough&quot; and, additionally there are thousands in the ME who would dearly desire to do harm in the EU and elsewhere but are and were thwarted.  Or else they are pretenders who don&#x27;t match their rhetoric.<p>If they want but can&#x27;t field hundreds in the EU (or other non ME&#x2F;NAf regions) does that not speak to current intel and ops being successful?<p>Your original assertion was &quot;But if anything the attacks prove that the whole surveillance thing isn&#x27;t effective, not that we need even more of it.&quot; To me, your responses seem to indicate the opposite [however that does not speak to the future]
