What role did TV play in the war?

Answer 1

This will depend upon what war you are asking about. In the United States, the first war to be shown regularly on TV was the Vietnam War. The images of fighting, of soldiers dying, of the jungles and civilians being burned and destroyed, caused a societal backlash against the war. This is generally considered one of the major reasons why the US public, and young adults in particular, turned against the war in Vietnam.
