Since his release from prison, Nelson Mandela has traveled 63,350 miles in 84 days to 23 countries, urging the retention of sanctions against South Africa and raising hackles by his refusal to denounce Fidel Castro and other revolutionaries who have supported his cause. The strain is showing: last week Mandela came down with mild pneumonia in Ethiopia. Mandela, who turns 72 this week, is considering a vacation that could raise some eyebrows: a three-week Caribbean sojourn as Castro's guest in Cuba.
