"...But that good will was fleeting. Swiss bankers and politicians have come to resent what they see as a squeeze on their most vital industry.

The strain is starting to show. This month, NEWSWEEK has learned, Swiss authorities threatened to throw a top U.S. congressional aide in jail as a spy if he tried to enter the country on official business. Douglas Frantz, chief investigator of the Senate Foreign Relations Committee, contacted the Swiss Embassy to set up meetings regarding a family facing trial for alleged nuke smuggling. As it turned out, the CIA had secretly recruited members of the family as informants, infuriating the Swiss. According to a U.S. official familiar with the matter who asked for anonymity when discussing a sensitive issue, Switzerland's police chief warned Frantz in an e-mail that he'd face arrest on espionage charges. Frantz, who declined to comment, canceled his trip. A Swiss spokesman said Frantz was turned away due to "ongoing" investigations, but that U.S.-Swiss relations remain "excellent."
