Atrios has the text of John Kerry's remarks to the senate all those years ago. Excerpted are some paragraphs that ring so true today...

In our opinion, and from our experience, there is nothing in South Vietnam which could happen that realistically threatens the United States of America. And to attempt to justify the loss of one American life in Vietnam, Cambodia, or Laos by linking such loss to the preservation of freedom, which those misfits supposedly abuse, is to us the height of criminal hypocrisy, and it is that kind of hypocrisy which we feel has torn this country apart.

Each day, to facilitate the process by which the United States washes her hands of Vietnam, someone has to give up his life so that the United States doesn't have to admit something that the entire world already knows, so that we can't say that we have made a mistake. Someone has to die so that President Nixon won't be, and these are his words, "the first President to lose a war."

We are asking Americans to think about that, because how do you ask a man to be the last man to die in Vietnam? How do you ask a man to be the last man to die for a mistake?

We are here to ask, and we are here to ask vehemently, where are the leaders of our country? Where is the leadership? We're here to ask where are McNamara, Rostow, Bundy, Gilpatrick, and so many others? Where are they now that we, the men they sent off to war, have returned? These are the commanders who have deserted their troops. And there is no more serious crime in the laws of war. The Army says they never leave their wounded. The Marines say they never even leave their dead. These men have left all the casualties and retreated behind a pious shield of public rectitude. They've left the real stuff of their reputations bleaching behind them in the sun in this country....
