I don't know if Cuba signed a treaty with the USSR to have nukes stationed on the island, but you're right that there was hypocrisy in putting US nukes in Turkey but forbidding USSR nukes in Cuba. Fortunately that was resolved amicably without the US invading Cuba. (Ironically, the Bay of Pigs Invasion occurred the year before the Cuban Missile Crisis).
