This guy seems to have it just right:

I do not want--as I believe most Americans do not want--to sell out American interests, to simply withdraw, to raise the white flag of surrender. That would be unacceptable to us as a country and as a people. But I am concerned--as I believe most Americans are concerned--that the course we are following at the present time is deeply wrong...

I am concerned--as I believe most Americans are concerned--that our present course will not bring victory; will not bring peace; will not stop the bloodshed; and will not advance the interests of the United States or the cause of peace in the world. I am concerned that, at the end of it all, there will only be more Americans killed; more of our treasure spilled out; and because of the bitterness and hatred on every side of this war, more hundreds of thousands of [civilians] slaughtered...

Isn't this exactly what we have always done in the past? If we examine the history of this conflict, we find the dismal story repeated time after time. Every time--at every crisis--we have denied that anything was wrong; sent more troops; and issued more confident communiques. Every time, we have been assured that this one last step would bring victory. And every time, the predictions and promises have failed and been forgotten, and the demand has been made again for just one more step up the ladder. But all the escalations, all the last steps, have brought us no closer to success than we were before...

Let us have no misunderstanding. [They] are a brutal enemy indeed. Time and time again, they have shown their willingness to sacrifice innocent civilians, to engage in torture and murder and despicable terror to achieve their ends. This is a war almost without rules or quarter. There can be no easy moral answer to this war, no one-sided condemnation of American actions. What we must ask ourselves is whether we have a right to bring so much destruction to another land, without clear and convincing evidence that this is what its people want. But that is precisely the evidence we do not have...

But the costs of the war's present course far outweigh anything we can reasonably hope to gain by it, for ourselves or for the [civilians]. It must be ended, and it can be ended, in a peace of brave men who have fought each other with a terrible fury, each believing he and he alone was in the right. We have prayed to different gods, and the prayers of neither have been answered fully. Now, while there is still time for some of them to be partly answered, now is the time to stop...

Amazing, isn't it? A critique of the war in Iraq that doesn't refer to the President as an incompetent, moronic criminal. A rational argument that acknowledges the complexity of the situation, the brutality of the enemy, and the difficulty of ending the war after having fought it for so long. Why, it's almost like the speaker is from an entirely different era, when politics was more about making your case than destroying the credibility of the other side.

Oh, who was the speaker? Sorry, forgot that detail - it was Robert F. Kennedy, circa 1968, speaking about the Vietnam war. As Glenn likes to say, read the whole thing.
