In this article, I argue that the introduction of ethnography to International Relations has not taken full advantage of the potential of bringing these two fields together. Using international intervention as an example, I suggest that to bring out this potential we need to be more attentive to the classical virtues of ethnography. This means taking the subjects of our studies much more seriously, as people capable of making sense of and reacting to the structures of power they are embedded in. Here implementers tasked to put international policies into action in relation to a concrete context provide an overlooked source of knowledge. Using their experiences, reflections and ways of dealing with the concrete dilemmas that arise in their daily work enables us to analyse intervention as concrete relations of power that play out, affect and are mitigated by people in the field. Seeing knowledge as in this manner arising from the field provides a deeper knowledge that is necessary if we want to read intervention not only as an exertion of power from the international to the local, but as dynamically reshaped, resisted and made sense of in the field.
