It can be applied to many situations, but I like to think of the Joseph Kony situation as more of a pyramid type structure. To that effect, I have come up with my own saying:
"Cut off the top of a pyramid..."
-
-
-
" ...and nothing much happens, because the infrastructure of the pyramid is still intact..."
-
-
-
" ...and there are like a 77 million pyramids in the world. It's true. I googled it."
-
-
-
But that doesn't really scan very well.
For more information about the KONY 2012 campaign, here is a link to an article about it, but you should probably read other articles too.
