I decided to look up the figures and it's not pretty... The "United Nations Department of Political and Peacebuilding Affairs" [prevention] had an income of $81m in 2020 whereas the "United Nations Department of Peace Operations" [mitigation] has a budget of $6.5b. And the UN has a budget of $3t! To over-simplify a bit: Cost(prevention) ~ 1% * cost(mitigation) Cost(prevention) ~ 0.0003% * UN Budget So essentially the global institution tasked with preventing conflict spends a rounding error of its budget doing so.
