There are two kinds of memories, and especially the memories of war are always of these two sorts. One is the public and official memory, and the other is the private and personal memory. The public memory is usually crystallized in state projects. In the case of the Vietnam War it is the Memorial Wall in Washington. The officials want a monument that endures through time. In America this can be a product of discussion and participation by many. And it is by discussion and participation that we have the Wall.
