So this poem won't fit everyone's interpretation of the meaning of today. But it is what I thought of. I've posted it before, but it seems appropriate to post it again to mark today's meaning as I experience it (knowing some will be offended by that interpretation just as some will be in agreement with it).
The Invasion of Grenada
I didn't want a monument,
not even one as sober as that
vast black wall of broken lives.
I didn't want a postage stamp.
I didn't want a road beside the Delaware
River with a sign proclaiming:
"Vietnam Veterans Memorial Highway."
What I wanted was a simple recognition
of the limits of our power as a nation
to inflict our will on others.
What I wanted was an understanding
that the world is neither black-and-white
What I wanted
was an end to monuments.
-- W. D. Ehrhart, 1984
(From Stewart O'Nan's anthology The Vietnam Reader, p. 679)
To all those today is meant to honor: RIP.
