The question is whether or not it's a good idea to have a single published document that contains the government's foreign policy for a particular region. Many other countries do this. I believe France has a written document that's updated every five years. I think the United Kingdom also has a written document for its foreign policy that's updated through a regular process. The U.S. government's position on various regions of the world is clear through their publication of documents.
We now have a situation where it's not clear what exactly the policy is. The department has 13,000 people or so. If you want to coordinate the department and the whole of government, having a single guiding document seems to me to make a lot of sense.
