going by firearm homicides from https://en.wikipedia.org/wiki/List_of_countries_by_firearm-r... and https://en.wikipedia.org/wiki/List_of_ongoing_armed_conflict... or https://en.wikipedia.org/wiki/List_of_ongoing_armed_conflict...

if my maths are correct, we have 4,5/100'000 firearm homicides reported for the US.

This is less than the hot conflicts (including, per TFA, the mexican drug war), and same order of magnitude, but still less than iraq (7/100'000 in 2019).

However, it's an order of magnitude more than ukraine (0,3/100'000 in 2019).
