Vietnam.

Explanation:

As US involvement escalated in the 1960's public support started to falter. The early optimism of a quick victory based on America's overwhelming military superiority slowly evaporated as the war dragged on.

Volunteers were replaced by conscripts and widespread TV coverage brought home the horrors of warfare. Events such as Tet and My Lai turned US public opinion against the war with the backdrop of the counter culture of the late 60's.
