President Eisenhower warned of the dangers of a high military budget and the militarism of the United States.
War actually serves several functions according to functional theory, but conflict theory emphasizes the many problems war causes and the role played in militarism by the military-industrial complex. Symbolic interactionism focuses on the experiences of soldiers and civilians in the military and in wartime and on their perceptions of war and the military.
War is best regarded as a social phenomenon rather than a biological phenomenon. Decisions to go to war are sometimes based on noble reasons, but they also involve deceit and prejudice.
The United States has the highest military budget by far in the world. Debate continues over the size of this budget; critics say that the United States would have a higher quality of life if the military budget were reduced and the saved dollars spent on unmet social needs.
Terrorism is best regarded as rational behavior committed for political reasons rather than as psychologically abnormal behavior. The US response to the 9/11 attacks has cost hundreds of billions of dollars, and critics say that the war on terrorism has both exaggerated the threat of terrorism and diverted attention and funds from unmet social needs.
