Some people in the U.S. government are the ones who promote much of the world terrorism. This is to give them an excuse to have a war on terror. Then, while they act like they are fighting terror, they do more terrorizing, just to promote the wealth of some wealthy people who pay them to terrorize covertly.
The US uses fear so that they would be needed and also to gain political and military influence around the world. Watch CNN and all you see is war, crime, terror. Imagine all the Americans watching this day in and day out brainwashing its citizens. Oh wait... CNN is now broadcasted all over the world and a lot of people from other countries need to know what's going on, so they watch it.
The point is do not fall prey to their predatory ways.
