…but what about the Nuremberg Code? Or human research protocols? Or that most intangible of standards, the Hippocratic Oath?

It was Greek, originally
As a refresher, the original HO, reproduced below:
I swear by Apollo Physician and Asclepius and Hygieia and Panaceia and all the gods and goddesses, making them my witnesses, that I will fulfil according to my ability and judgment this oath and this covenant:
To hold him who has taught me this art as equal to my parents and to live my life in partnership with him, and if he is in need of money to give him a share of mine, and to regard his offspring as equal to my brothers in male lineage and to teach them this art – if they desire to learn it – without fee and covenant; to give a share of precepts and oral instruction and all the other learning to my sons and to the sons of him who has instructed me and to pupils who have signed the covenant and have taken an oath according to the medical law, but no one else.
I will apply dietetic measures for the benefit of the sick according to my ability and judgment; I will keep them from harm and injustice.
I will neither give a deadly drug to anybody who asked for it, nor will I make a suggestion to this effect. Similarly I will not give to a woman an abortive remedy. In purity and holiness I will guard my life and my art.
I will not use the knife, not even on sufferers from stone, but will withdraw in favor of such men as are engaged in this work.
Whatever houses I may visit, I will come for the benefit of the sick, remaining free of all intentional injustice, of all mischief and in particular of sexual relations with both female and male persons, be they free or slaves.
What I may see or hear in the course of the treatment or even outside of the treatment in regard to the life of men, which on no account one must spread abroad, I will keep to myself, holding such things shameful to be spoken about.
If I fulfil this oath and do not violate it, may it be granted to me to enjoy life and art, being honored with fame among all men for all time to come; if I transgress it and swear falsely, may the opposite of all this be my lot.
One could argue many points in the traditional Hippocratic oath, particularly the “I will not give to a woman an abortive remedy” bit. So much so, that the modern version dispenses with some of its tenets entirely. The underlined ones above, however, seem pretty universal. And while it would take a superhuman doctor to fulfill all of these ideals, it should be our aim as physicians at least to strive for them.
The behavior of the CIA doctors, who not only monitored interrogations and helped conduct waterboarding sessions, but also gathered data (as yet unconfirmed by the CIA) to “improve” said interrogations, has come under scrutiny from a variety of media and human rights organizations. Most egregious is the fact that their function was to serve “no therapeutic purpose”.
In the past few months/weeks/days, their actions have been widely decried on international and historical grounds. Comparisons have been drawn to the horrifying experiments of Nazi doctors; the specter of eugenics has once again been raised; and, reaching back even further, this recalls the ways in which scientific research allied itself with the imperialist project.
As future medical professionals, we must consider all of these things. But we must also consider the widespread ethical implications of international human subjects research and our roles as physicians. We will all conduct research, many of us abroad. And while the Guantanamo Bay detainees were a unique population, their situation has interesting parallels to other research subjects –international patients, populations that should be protected, or populations whose standard-of-care is lower than our own. The CIA fracas is an extreme example, a crystallization of these questions. It bothers us precisely because it summons the specter of our murky medical past.
