Propaganda in the United States
Aspects of Propaganda can be traced back since the founding of the United States , with its use being vital as casus bellis for wars such as the Spanish-American War of 1898 , which led to the practice of yellow journalism , the Gulf of Tonkin incident which led to the Vietnam War , the Nayirah testimony prior to the Gulf War , and reports of Saddam Hussein's alleged shredder as well as the conjecture of WMD's in Iraq which was the main rationale behind the invasion in 2003 .
