You nailed it, I think. If surveillance works, then Paris, Beirut, Bagdad et al wouldn&#x27;t have happed. Realizing it&#x27;s a pipe dream, I&#x27;d love to see a world accept that we the west have done so much damage that nothing will stop terrorism.<p>Accepting that means we can throw those wasted resources at things that have a better chance of working - throw the tech that detects copyright infringements at detecting pro-ISIL sites, and use DCMA-style tactics to take them down. Fund new research to put effective bomb and weapon detectors into every doorway. Because protecting borders doesn&#x27;t work either (crunchy on the outside, soft on the inside). Build schools, instead of bombing them. Stop selling weapons to the very people that shouldn&#x27;t have them. Teach politicians to value non-American lives as much as American ones. Stop honouring violent death, and honour the deaths of people who move humanity forward instead.<p>There&#x27;s an endless stream of ideas of what we <i>could</i> do, if only we actually <i>wanted</i> it.
