This chapter discusses Norwegian perspectives on North Atlantic Treaty Organization (NATO), and security and defense policy. It begins with a short background discussion about the historical relations between Norway and Russia, and the Norwegian security and defense posture that has resulted in since the World War II. It describes Norway’s relations to NATO, popular support for the Alliance today, and Norway progress concerning the 2 percent target at the Wales summit in 2014. Current Norwegian security and defense policy reflects renewed concerns about developments in Russia, and the desire to enhance NATO and United States engagement in the north, while also strengthening European security cooperation. Norway, as a small state with limited national forces, must rely on NATO for its security and deterrence. Norwegian popular support for NATO is higher than in a long time, and even voters on the far left appear predominantly supportive.
