FILE - In this April 9, 1953 picture, members of the Iroquois dance on the lawn of the Vermont State Capitol building in Montpelier, Vt. to protest land taken by the state. An American Indian lacrosse team's refusal to travel on passports not issued by the Iroquois confederacy goes to the heart of one of the most sensitive issues in Indian Country _ sovereignty. The rights of Native nations to govern themselves independently has long been recognized by federal treaties, but the extent of that recognition beyond U.S borders is under challenge in a post-Sept. 11 world.
