There have been some challenges by us in the U.S. actually under existing WTO rules with regard to, say, hormone use in beef, and things of that nature. One can have different views about that, but in Europe certainly they have taken the view that they're very concerned about the quality and safety of the food that is imported. Again, my sense is that these kinds of decisions are ones that government should make on the basis of the best health policy that's out there. They should not be overturned because they violate a particular trade rule.
In all of this there have been trade challenges aside from tobacco and aside from alcohol. One of the things that we did, which we arguably should be very ashamed of, was in 1996, we challenged France's ban on asbestos. We know that asbestos kills something like 106,000 people a year, according to the WHO. We went to the WTO to overturn a ban on a product that we knew kills people.
