tldr: In 2002 and 2003 combined, there were 9 terror attacks with 23 casualties across all of Africa. After the US war on terror campaign in Africa, things are now much much worse. And it looks like this stat doesn't include numbers from direct US acts of terror, like the destruction of Libya in 2011.
There are US empire supporters who will say that this is OK since this is the result of US trying to own the region that rightfully the US should own, but a lot of this is also the US military trying out new weapons, tactics, strategies and just having fun in their own way.
You really should disable that thing, you know.
