War is an Instrument of Policy

Clausewitz in On War, 1873:

[W]hen people speak, as they often do, of the prejudicial influence of policy on the conduct of a war, they say in reality something very different to what they intend. It is not this influence but the policy itself which should be found fault with. If policy is right, that is, if it succeeds in hitting the object, then it can only act on the war in its sense, with advantage also; and if this influence of policy causes a divergence from the object, the cause is only to be looked for in a mistaken policy.

It is only when policy promises itself a wrong effect from certain military means and measures, an effect opposed to their nature, that it can exercise a prejudicial effect on war by the course it prescribes. Just as a person in a language with which he is not conversant sometimes says what he does not intend, so policy, when intending right, may often order things which do not tally with its own views.

This has happened times without end, and it shows that a certain knowledge of the nature of war is essential to the management of political commerce.

President Bush on Meet The Press, February 8, 2004:

President Bush: I'm a war president. I make decisions here in the Oval Office in foreign-policy matters with war on my mind. Again, I wish it wasn't true, but it is true. And the American people need to know they got a president who sees the world the way it is. And I see dangers that exist, and it's important for us to deal with them.

... Russert: Were you favor of the war in Vietnam?

President Bush: I supported my government. I did. And would have gone had my unit been called up, by the way.

Russert: But you didn't volunteer or enlist to go.

President Bush: No, I didn't. You're right. I served. I flew fighters and enjoyed it, and provided a service to our country. In those days we had what was called "air defense command," and it was a part of the air defense command system.

The thing about the Vietnam War that troubles me as I look back was it was a political war. We had politicians making military decisions, and it is lessons that any president must learn, and that is to the set the goal and the objective and allow the military to come up with the plans to achieve that objective. And those are essential lessons to be learned from the Vietnam War.

John Kerry speaking to the Senate Foreign Relations Committee, April 23, 1971:

We saw first hand how monies from American taxes were used for a corrupt dictatorial regime. We saw that many people in this country had a one-sided idea of who was kept free by the flag, and blacks provided the highest percentage of casualties. We saw Vietnam ravaged equally by American bombs and search and destroy missions, as well as by Viet Cong terrorism - and yet we listened while this country tried to blame all of the havoc on the Viet Cong.

We rationalized destroying villages in order to save them. We saw America lose her sense of morality as she accepted very coolly a My Lai and refused to give up the image of American soldiers who hand out chocolate bars and chewing gum.
...
We are here in Washington to say that the problem of this war is not just a question of war and diplomacy. It is part and parcel of everything that we are trying as human beings to communicate to people in this country - the question of racism which is rampant in the military, and so many other questions such as the use of weapons; the hypocrisy in our taking umbrage at the Geneva Conventions and using that as justification for a continuation of this war when we are more guilty than any other body of violations of those Geneva Conventions; in the use of free fire zones, harassment interdiction fire, search and destroy missions, the bombings, the torture of prisoners, all accepted policy by many units in South Vietnam.
...
We wish that a merciful God could wipe away our own memories of that service as easily as this administration has wiped away their memories of us. But all that they have done and all that they can do by this denial is to make more clear than ever our own determination to undertake one last mission - to search out and destroy the last vestige of this barbaric war, to pacify our own hearts, to conquer the hate and fear that have driven this country these last ten years and more. And more. And so when thirty years from now our brothers go down the street without a leg, without an arm, or a face, and small boys ask why, we will be able to say "Vietnam" and not mean a desert, not a filthy obscene memory, but mean instead where America finally turned and where soldiers like us helped it in the turning.
