The Swedish defence is being deeply reformed. Based on territorial defence during the Cold War, it is now based on flexible operational forces to be used both nationally and internationally, and centralised in a single operational and tactical command. However, the development of their interoperability with NATO must be an incremental process seen in a long-term perspective. Such a reform requires public support and a large participation of varied actors. There has been an intense debate and a political consensus has been reached on Swedish defence policy.
