However, I knew I had already read roughly the same material a number of years ago. I found the article, and it was in fact worse than both the Guardian article and my own recollection. It was in The Atlantic:
In March of 1998, on a visit to Rwanda, President Clinton issued what would later be known as the "Clinton apology," which was actually a carefully hedged acknowledgment. He spoke to the crowd assembled on the tarmac at Kigali Airport: "We come here today partly in recognition of the fact that we in the United States and the world community did not do as much as we could have and should have done to try to limit what occurred" in Rwanda.
This implied that the United States had done a good deal but not quite enough. In reality the United States did much more than fail to send troops. It led a successful effort to remove most of the UN peacekeepers who were already in Rwanda. It aggressively worked to block the subsequent authorization of UN reinforcements. It refused to use its technology to jam radio broadcasts that were a crucial instrument in the coordination and perpetuation of the genocide. And even as, on average, 8,000 Rwandans were being butchered each day, U.S. officials shunned the term "genocide," for fear of being obliged to act. The United States in fact did virtually nothing "to try to limit what occurred." Indeed, staying out of Rwanda was an explicit U.S. policy objective.
I was quite surprised to find that our friend Dick Clarke makes an appearance. I wonder why he never wrote a book about this:
Against this backdrop, and under the leadership of Anthony Lake, the national-security adviser, the Clinton Administration accelerated the development of a formal U.S. peacekeeping doctrine. The job was given to Richard Clarke, of the National Security Council, a special assistant to the President who was known as one of the most effective bureaucrats in Washington. In an interagency process that lasted more than a year, Clarke managed the production of a presidential decision directive, PDD-25, which listed sixteen factors that policymakers needed to consider when deciding whether to support peacekeeping activities: seven factors if the United States was to vote in the UN Security Council on peace operations carried out by non-American soldiers, six additional and more stringent factors if U.S. forces were to participate in UN peacekeeping missions, and three final factors if U.S. troops were likely to engage in actual combat. In the words of Representative David Obey, of Wisconsin, the restrictive checklist tried to satisfy the American desire for "zero degree of involvement, and zero degree of risk, and zero degree of pain and confusion." The architects of the doctrine remain its strongest defenders. "Many say PDD-25 was some evil thing designed to kill peacekeeping, when in fact it was there to save peacekeeping," Clarke says. "Peacekeeping was almost dead. There was no support for it in the U.S. government, and the peacekeepers were not effective in the field." Although the directive was not publicly released until May 3, 1994, a month into the genocide, the considerations encapsulated in the doctrine and the Administration's frustration with peacekeeping greatly influenced the thinking of U.S. officials involved in shaping Rwanda policy.
