i think massive traumatic events also result in a kind of PTSD at the level of population, and unfortunately there is not much we know what to do with it.
Couple other notes. The conspiracy theory is that the Mozambique destination was just a cover, and the AN was intended for Hezbollah. The Hezbollah affiliated company tried to buy the arrested AN, and failing that, Hezbollah was also stealing that AN which was conveniently stored in an unguarded warehouse with broken door and a hole in the fence walls - for years despite numerous alarms raised by various people/agencies.

Also interesting that AN seemed to be Nitroprill as seen on the photo in the article (https://pbs.twimg.com/media/EeowoGhVoAM2_zs?format=jpg&name=...) - googling shows that it is a bit more stable form of AN.
