After negotiations with representatives of the Cuban government, Clinton revealed in May 1995 a controversial policy reversing the decades-old policy of automatically granting asylum to Cuban refugees. Approximately 20,000 Cuban refugees detained at Guantanamo Bay Naval Base in Cuba were to be admitted to the United States over a period of three months. In order to prevent a mass exodus of refugees to the United States, all future refugees would be returned to Cuba. The influx of refugees into Guantanamo Bay overwhelmed the facilities, necessitating Operations Safe Haven and Safe Passage involving Panama. Clinton also implemented the wet foot/dry foot policy for Cuban refugees. This policy meant that Cuban refugees caught at sea were returned to Cuba (wet foot), while Cuban refugees that made it to dry land (dry foot) were allowed to stay in the U.S. This changed the refugees' tactics from slow rafts to speed boats.
