U.S. State Department Background Notes: Sweden "Swedish foreign policy is based on the premise that national security is best served by staying free of alliances in peacetime in order to remain neutral in the event of war...During the جنگ سرد، Sweden was suspicious of the superpowers, which it saw as making decisions affecting small countries without always consulting those countries. With the end of the Cold War, that suspicion has lessened somewhat, although Sweden still chooses to remain nonaligned."
