I don't think the Scandinavian/Nordic countries were ever actually neutral or non aligned/committed. Even during the 2006 NATO Red Flag military drills, Sweeden was committed to taking the side of "the West" should a NATO country be attacked. This position was made public by having four Gripen military fighter jets participate in the NATO manoeuvre Red Flag back then, where an attack on a NATO country is used as a scenario to test combat readiness. The Gripen jets were even made fully compatible with NATO standards during the manoeuvre. Denmark sent troops to Iraq.

So there is only a surrendering of official/public non committance/neutrality, as in reality Nordic countries have made their commitment to being NATO aligned quite clear over the past few decades.
