The United States recently "lend[ed] its support" to the Declaration on the Rights of Indigenous Peoples (DRIP). The US had not voted for the Declaration when the General Assembly adopted it in 2007. Canada, Australia, and New Zealand also did not vote Yes at that time, but all three states have since endorsed the Declaration; the US is the latest and last. It must be remembered that the Declaration is not a treaty, and is therefore not legally binding. President Obama announced this "change of position," attributing it in part to Native Americans' persuasion and perseverance on the issue.
President Obama told the White House Tribal Nations Conference in December 2010:
But I want to be clear: What matters far more than words -- what matters far more than any resolution or declaration -- are actions to match those words. That's the standard I expect my administration to be held to.For complete details: Announcement of U.S. Support for the United Nations Declaration on the Rights of Indigenous Peoples" Statement by U.S. Government December 2010.
