The NATO Association of Canada just had an event that looked at the responses to terrorism that are possible through NATO. It is an extremely important issue. With regard to our friends to the south, Mr. Trump has specifically highlighted this as something NATO should be considering as an existential threat to all democracies and to NATO itself. It's a challenging thing for NATO to take on. Most of the experts I have spoken to, and who have been part of the NATO Association, consider terrorism and management of terrorism to be a much more local jurisdiction, and that this is very often the best way it can be counteracted.
If we're talking about intelligence sharing, that's a horse of a different colour. NATO has always been good at that, despite the several different layers of intelligence networks within NATO.
I think that's where the real two situations of terrorism are shown in NATO. One is intelligence, which NATO should be trying to make sure runs much more smoothly through the alliance. The other is actual deterrents, whether deradicalization or counterterrorism, which are usually much more usefully dealt with at the local level.
