The text was removed because it was not appropriate for the topic (please see the Wikipedia help: What wikipedia is not). While I did not disagree with what the text said I felt it belonged in a topic dealing with the cold war such as NORAD. I also felt it was not NPOV as it presented only one side of the affair, however this was not the main reason for removing it. If you feel that information on the Artic requires a information on it's uses for Nuclear Weapons please include all sides of the issue, mainly that multiple countries around the world use artic waters to deploy nuclear submarines aswell as air defense. However, a See Also reference to NORAD would be more appropriate.
