> That's interesting, but what's puzzling me the most is how less people commit suicide during a war.

Just speculating, but, I can immediately see two obvious potential contributing factors to lower suicide statistics (one of which isn't actually about reduced incidence of suicide, per se): during a war, there's a lot more opportunity for suicide-that-doesn't-get-categorized-as-suicide, and there is also a additional opportunity (compared to peacetime) for things that provide short-term, immediate purpose even if they don't deal with the underlying problems.
