Abstract
Since the Allies landing in July 1943, Sicily’s role as an armed island under the control of the United States of America with an anti-Soviet function was defined. A long process of militarization begins. In 1981 the decision by the USA and NATO to install 112 nuclear-tipped Cruise missiles in Comiso provoked the development of an important pacifist and anti-militarist struggle with anarchists among the main protagonists. In the summer of 1983, the attempts to occupy the base and the protests met with a harsh police reaction which sealed the defeat of the movement. Almost thirty years later in Niscemi the installation of the MUOS satellite communications system met with a strong popular reaction which put the usa in difficulty; antimilitarism proves capable of hindering war projects, as happens in the acute phase of the conflict. The fight continues today.
