Although it does sound quite reasonable, I am not sure if everything
they tell is true. I heard and read some negative about it, like America
just helping in order to get influence on the Ugandan oil industry etc. Not
saying those negative comments are the whole and only truth, but I am
bit cautious.
The thing making me the most cautious with actually undertaking any
action, as the video wants people to, is how scary all those teenagers
look as they scream for justice all together. All what is needed is an evil
leader of the group they are part of ('Invisible Children') and they might
following him blindly to start World War II revisited...
(p.s. my vision is inspired by a German movie I watched some years ago,
named 'Die Welle' :
