The U.S.'s forever wars are kept out of sight, and sound, and out of the media for a reason - it's bad public relations. The U.S. learned the lesson of an open un-embedded press from the Vietnam war, and it's bad ramifications in public relations. 

Today there is a strict lock on how our endless, self-created conflicts are reported, and that creates the disconnect between the military and the public. There is no discussion of what our wars mean in the public domain. In this context it is quite easy to understand how Memorial Day lost its meaning.
