The US worked with Lucky Luciano and the mafia during World War 2. Luciano provided intelligence help to disrupt German spies and sabotage in exchange for reducing his prison sentence. The US then worked with Sicilian mafia boss Calogero Vizzini during the invasion of Sicily in 1943. Vizzini aided the Allied troops' movement and was later appointed mayor of his hometown by the US as a reward for his assistance. The cooperation between the US and mafia provided benefits for both sides during the war, despite their opposing interests.
