I dont think it can simply be whether or not youre likely to be in a literal warzone if Haiti and the US are like 9 spots apart. It must be odds of being a victim of violence in general. Haiti has a lot of gang violence and basically no effective policing. The US has policing that may ultimately result in you being a victim of violence, plus more guns per capita than anywhere else in the world. I can see those things balancing out to being close on the list, but in the US you would not be likely to end up “in a warzone”. Youd be likely to get killed in other ways though
