War and public relations - these are two inseparable concepts. The first one probably wouldn’t have place in human world if it wasn’t for the other one (though PR is often thought to be a modern profession its roots are thousands years old). And as I wrote before governments use public relations and propaganda to manipulate their audiences and gain their support in many issues; one of them is war.
Film made by BBC ‘War Spin’(2003) shows very well how US Department of Defence used public communications to maintain certain image of American and British troops and actions they were taking in Iraq. The ‘tool’ that made creation of that image possible was control of the media and messages sent into the world. I think this is one of the most important things in propaganda, to control the media: radio, TV, papers, online. After all, media are the fourth power and probably everyone heard that saying: “whoever controls the information controls the world.”
