Although this book is a bit dated (it was published in 1998), it provides great information on how the embargo affects the Cuban people. More importantly, it distinguishes between two interpretations of human rights: 1) political/civic/individual and 2) social/economic/collective. This, Schwab argues persuassively, underpins some of the tension between Cuba and the US.
He also presciently notes what would happen when Raúl Castro came to power.
I use this book for the class that I teach and I highly recommend it. Much of what Schwab writes remains very relevant as Donald Trump prepares a new assault on Cuba.
