There ought to be a branch of the military that is dedicated to those goals.
I can imagine there are a lot of people who might be interested in that, but not in the war fighting. Today those people either don't enlist, or enlist and hate that aspect.
Not the military, that's what the State Department is for. Or the UN.
Edit: Ok maybe not what it's for, but the State Department is a better fit. Nobody is ever going to trust a foreign military to do anything good in their country.
