Because, once the military has used you up, physically and psychologically, the bureaucracy tosses you aside like a piece of shit.
Some folks are noticing, finally.
Here's an editorial from Daytona Beach, Fla, which ends:
The numbers, the lost lives and broken promises to veterans ought to be a national shame for a country so gushy with "Support Our Troops" rhetoric toward men and women who supposedly "live in honor among us, or sleep in valor beneath this sacred ground," as President Bush described them in a speech from Arlington National Cemetery last Veterans Day. That so many veterans end up in more proximity to gutters than honors shows to what extent the rhetoric is less than what it seems with its $2 yellow-ribbon stickers on the back of cars and a veterans' mental care system stuck in the middle of the last century.
The standing army is a threat to democracy, always has been.
But just discarding the injured and the wounded is a threat to our humanity.
