William S. Farish, the owner of Lane's End Farm and U.S. Ambassador to Great Britain, says the possibility of a military conflict between the United States and Iraq brings into question the status of the $6-million Dubai World Cup at Nad Al Sheba Racecourse in the United Arab Emirates on March 29.In an exclusive interview with the Lexington Herald-Leader on the topic of the pending war, Farish said American horsemen should be concerned about traveling to Dubai for the World Cup."I think it's going to be a very tough decision for them," Farish told the newspaper. "Nobody knows whether we're going to war or not, or how long it's going to last if we do."In the interview, Farish said the decision by President Bush on whether to declare war could come as early as today and is likely to be finalized by the end of next week. "I think it's going to come to a head very soon," Farish said.
