The modern war itself is a media event and the media are the center of gravity. However, researchers consider the traditional term ”public relation” unable to express its complexity. The more appropriate one should be ”strategic communication.” This study uses historical research and documentary analysis to discuss the strategic communication of US armed forces in Persian Gulf War in 2003. It analyzes the application of the media from three perspectives which include public diplomacy, public affairs and psychological operation. Then it ends by reviewing these strategic communications. Wars are usually full of lies and disguises. The conclusion of this study is that the modern war executes the essential of information dissemination by credibility listening and effective means. Nevertheless, different objects should be separated and given different kinds of information. This is the way to get rid of the tangle of the truth and lies, which is also the best way to obtain hearts and minds.
