The Skull in the picture represents death and destruction. The Black stand is that of a Globe. The Globe represents humanity.
The Globe along with its stand has been smashed into the Skull. The world has been represented in Red color to represent death and bad times over it. The breaking of the Skull all over the Globe makes up the whole concept.
The Eye ball out of the skull lying in front with "When will it end" written in it, shows that Humanity has had enough of all this and needs it to stop.
Hence, terrorism needs to stop, or it will take over the world, and destroy all of it.
