RUSSELS -- Last week I went to lunch at the Hotel Schweizerhof in Davos, Switzerland, and discovered why America and Europe are at odds. At the bottom of the lunch menu was a list of the countries that the lamb, beef and chicken came from. But next to the meat imported from the U.S. was a tiny asterisk, which warned that it might contain genetically modified organisms — G.M.O.'s.

My initial patriotic instinct was to order the U.S. beef and ask for it "tartare," just for spite. But then I and my lunch guest just looked at each other and had a good laugh. How quaint! we said. Europeans, out of some romantic rebellion against America and high technology, were shunning U.S.-grown food containing G.M.O.'s — even though there is no scientific evidence that these are harmful. But practically everywhere we went in Davos, Europeans were smoking cigarettes — with their meals, coffee or conversation — even though there is indisputable scientific evidence that smoking can kill you. In fact, I got enough secondhand smoke just dining in Europe last week to make me want to have a chest X-ray.

Ah, Those Principled Europeans
