Système monétaire européen
The MSI took a strongly nationalistic approach in foreign policy, but was initially divided between "third force" and pro-NATO groups. It abstained when the parliament voted on Italy's admission into NATO in 1949, but later expressed support for NATO and the European Community, based on a "European nationalism" idea. The party supported Italy's inclusion in the European Monetary System in 1979, as well as the installation of American cruise missiles in Sicily in 1983.
