Since 2006, Uganda discovered world class oil fields along its border with DRC. The location of the oil fields has raised the stakes for the Ugandan military and its regional partners, including the US.

It would be great to get rid of Kony. He and his forces have left abductions and mass murder in their wake for over 20 years.

But let's get two things straight:
1) Joseph Kony is not in Uganda and hasn't been for six years;
2) The LRA now numbers at most in the hundreds
Looks like I was wrong then! Am at work, so can't check the links from Seraph, but the Ugandan student interviewed by the Guardian seems to think it's both cynical, patronizing and possibly financially dubious. And that's not even mentioning the idea of American and other school children financing purchase of weapons for the regular army of a corrupt African state. The more I think about it, the more questionable the whole thing seems.

The thing that is new and interesting about this is the fact that it's all done via social networking. But so, I understand, are phenomenons like Occupy Wall Street and "Anonymous".

I have long been of the opinion that foreign aid to Africa achieves little, mostly ends up with corrupt locals and may also create a dependency and a lack of initiative and victim mentality in the recipient countries. The aid policy of my own country has been incredibly bizarre and contradicting through the years and it's beginning to be clear that most initiatives have achieved very little. In the UK there is a large debate about why the UK is giving aid to India, a country with a space program, or China a country that is rapidly buying up British businesses.

If I was a super cynical extremely anti-US journalist, then I'd say along the lines of some Russian tabloids that this could be fake, perhaps with some intelligence backing. "We don't want to invade [oil rich] Uganda, but our citizens are begging us to, and Kony is sooooo evil".
I'd stop short of that though, because it is too much of a consipiracy theory.
