I am in the process of reviewing the report that I received to make a policy recommendation. I will say, though, that I haven't been told by the U.S. which study they used to base their policy decision on, nor have I been told by the Germans which studies they used to base their policy decision on. I would be interested to know which studies they used to do that. I do have contact with those organizations and have had discussions with them.
