Cuba has a population of about 11 million. There are only an estimated 1,500 Jews left in Cuba, a far cry from the 15,000 in 1959 when Fidel Castro came to power. There are five synagogues on the island: three in Havana, one in Santiago and one in Guantanamo. Throughout our week in Cuba, we visited all five and met with their leaders and members.
From what we could see, there seems to be minimal anti-Semitism in Cuba and there is a memorial to the Holocaust in the center of Havana.
I encourage you to consider joining a mission and see Cuba for yourself.
