Acheson was particularly worried that allowing the details of the coup to go public would damage the image of the US. Under the Rio Pact of 1947, the Organization of American States (OAS) had obtained jurisdiction over regional disputes from the United Nations. To achieve this, the US had also committed to a policy of non-intervention in the internal affairs of other countries. If PBFortune had become public knowledge, the fact that the US was supporting an invasion of a fellow member of the OAS would have represented a huge setback to US policy, thus motivating the State Department to end the operation when they became aware its cover had been blown.
