After Russia’s aggression against Ukraine in February 2014, the Swedish thinking about its defense has changed remarkably. Like most of Europe, Sweden had steadily disarmed for a quarter of a century after the end of the Cold War, and its military expenditure had sunk to 1 percent of gross domestic product (GDP). Russia’s actions against Ukraine woke Sweden up. Swedes got upset, while the Finns were worried. Together with Poland and the three Baltic states, Sweden has been among the European Union countries most committed to sanctions against Russia over Ukraine.
