Public relations coup for Castro government

That's how the Guardian sees the story.

"Eight American students have graduated from a Cuban medical school after six years of free tuition, giving a fresh boost to the reputation of the communist government's health care system."

Meanwhile, in the real world Cuban Doctors defecting to the United States. Why you may ask.

"The policy offers the Cubans a tempting opportunity. Back home they face a life of poverty under a Communist regime that offers few political rights, whereas in the USA, because of their professional skills, they have a chance to move quickly into a comfortable middle class life."
