Kony exists and for virtually no effort on our part (Facebook here, phone call there, etc.) we can make sure the US government will keep helping...
Well I don't know about you but I sure as hell have no chances of having any kind of effect with US goverment.
And I think the key point with this military operation here isn't even in having US goverment to help but to have the actual central african countries take control and do it by themselves.
That's why the hundred military personnel are there to give consultation. And also so that after this possible problem is solved in some way, they can then concentrate on Somalia, yet again invidually, not with the aid of US military.
I think the articles presented on the last page especially this one:
