Brings to mind Churandy Martina, who used to compete for the Dutch Antilles but now competes for the Netherlands. Only in his case, after some political reorganisation, his country disappeared!
The IAAF no longer acknowledges the Netherlands Antilles as a country.
The only exception remains Aruba, but the athletes of all other Antilles Islands will have to compete for the Netherlands.
Martina has always freely chosen to compete for Curaçao (ie part of the NA) even though he could have run for The Netherlands.
"It has been for all of us a surprise..."
