So apparently the Iroquois Confederacy has been trying to get to the World Lacrosse Championships held in the United Kingdom, and have not been allowed entry because they have been using Iroquois passports (which have been accepted for 30+ years, apparently out of courtesy).
Two articles on the issue:
Here is an article that describes how they've had to forfeit the first game dur to the passport issue. ... and another describing how those the issue has sparked futher feelings of nationalism in Quebec. It's certainly a very complicated issue, certainly, and I'd love to know what you guys (and gals) think!
