We currently have global war, it’s just that the media is not portraying it as a unified attempt at domination. All the players have their hands in the game.
This comes from one side of the war and they have a stated purpose of world domination. Warning graphic images of death. http://rt.com/news/176528-islamic-state-iraq-video/
Other groups and nations have made similar statements wanting to dominate the world under their control and destroy all vestiges of other cultures. These images are what they have in mind for the rest of the world.
edit: or am I just paranoid?
