This article investigates the Swedish decision to participate in Operation Unified Protector in Libya and the Finnish decision to refrain from the same operation. It takes as its theoretical point of departure the concept of strategic culture and argues that differences in the strategic culture of the two countries contributed to the differences in behavior toward the Libya intervention. The Finnish and Swedish strategic cultures differ with respect to the core tasks of the armed forces, willingness to use force, and with respect to what types of operations and organizational frameworks Finland and Sweden find it appropriate to participate in.
