African politics and conflicts can't be approached with such simplicity. Most of times when a nation is willing to send aid to an african country in war it is to gain their sympathy or in exchange for something with the local -crooked government, since most of that food is going to end in the military stomach. Nobody is going to enforce the fair distribution, the blue helmets are just scarecrows with little to none intention to fuck around with the rebels or the local forces. At their best they will just give the food or medical goods to the people, and then those will be savaged and robbed when they get out of the UN perimeter, all with the local government/ruling rebel group consentement.
Seriously, most Africa is a hellhole, nobody wants to put soldiers on their soil for a good reason (except the old metropolis, which will send happily their green berets and mercenaries to protect the national monopolies). France is probably defending their interests, while the amicable countries, so well intentioned now, didn't gave a fuck when the situation was already terrific but stable, and now they are trying to get a piece of the cake taking advantage of the situation (and proclaming themselves the good while taking a piss on the french).
Sometimes I think that the only way to heal Africa is to nuke the hell out of the continent. I know a photographer from an old work that was unemployed due a depression for almost a year after being in Zimbabwe some time ago.
