The Marianas Variety says National Geographic names Guam one of the 'last colonies'. Sure enough, June's Last Colonies article doesn't say much, but Guam's on the list.
In fact, the author refers to 'the committee that deals with the issue', he can't even tell us it's the Special Committee on Decolonization, also known as the Fourth Committee. Here's a pretty up-to-date blog.
The Committee wants wants "non-self-governing" territories to settle their status by 2010. Not likely since the controlling countries, particularly the United States and the United Kingdom, view the Fourth Committee as a relic of the Cold War. The name doesn't help in nixing that impression.
I've never understood why the U.S. doesn't just finally deal with the issue. Guam deserves a vote, whatever the outcome.
