Pituffik or Thule in Greenland has always been controversial within foreign and security policy between three parties: Denmark,Greenland and the USA. The Thule-base in Greenland has had an important role during the Cold War as part of the US military sphere in the North. The role of the base has changed over time to become a radar station, but it is still part of the overall US defense system. Recent tensions around the base regarding the contract and subcontractor’s role have intensified discussions about the existence of the base and who actually has power over the base. The Greenlandic government has had awish to be more influential on what is going on in the far north, but things have been held secret from the public and local politicians. This has resulted in some skepticism between Greenland and Denmark on the one hand, but also between Greenland and the USA on the other. This paper will shed light on the development from the bilateral to the trilateral relationship outplayed between the three major actors and how this relates to foreign and security policy within the Kingdom of Denmark and the relationship towards the USA.
