It's been said that the nation that forgets it's defenders will also be forgotten.
It is our duty to honor and remember those who paid the ultimate sacrifice. As a nation we say, 'You are not forgotten.' However, often I think we mean it as a whole. The entire group is remember as a group and honored as a group that will not be forgotten. This wall is a way to say individually to each and every person YOU ARE NOT FORGOTTEN.
It's a way to let the Gold Star Families know that someone knows the name of their loved one and remembers them and honors them for everyone to see.
