The American public's support of the Iraq War and the War on Terror in the current day is generally low. A majority of Americans now view the Iraq War as a mistake and believe that it did not achieve its stated goals. This change in support is primarily due to the fact that the reasons given for the invasion, namely the presence of weapons of mass destruction and ties to terrorism, were later revealed to be false or overstated. Additionally, the length and cost of the war, as well as the high number of American casualties, have contributed to growing skepticism and opposition to the war.
A strong point of comparison to the American public’s support of the Iraq War and the War on Terror today is the American public's support of the Vietnam War. Both conflicts have been long-lasting, and costly and resulted in a significant number of American casualties. However, the difference in the public support of the two wars is significant. During the Vietnam War, public support for the war began to decline as the conflict dragged on, and the public became disillusioned with the government's handling of the war. This led to a widespread anti-war movement and widespread protests. In contrast, public support for the War on Terror and the Iraq War has declined gradually over time, as more information has come out about the reasons for the war, the cost, and the consequences.
It is important to note that the public opinion on wars can change with the time, and it can be influenced by many factors such as the effectiveness of the war, the number of casualties, the media coverage, and the political climate.
