Norwegian security policy has had a transatlantic foothold for at least 70 years. For the foreseeable future, the US will remain Oslo’s most important security guarantor and its most important defence and security partner. However – and regardless of who is in the White House – Norway must prepare for the impact of major shifts in US policy and Washington’s pivot to Asia.

Meanwhile, and particularly in the aftermath of Brexit, the UK has the ambition to be a global security player, with a particular focus on Northern Europe. In this context, there may be opportunities for the UK and Norway to further strengthen bilateral defence and security policy cooperation, with the UK’s close ties with the US further strengthening Norway's relationship with both countries.

This project is run in collaboration between RUSI in London, the Norwegian Institute of International Affairs (NUPI) in Oslo and the Center for Strategic and International Studies (CSIS) in Washington.
