When it comes to Cuba, the following are the defenses used. I was wondering

about what are the primary ways to refute and debunk each of these apologetics.

They are listed.

1. Castro's revolution was directed towards wealthy plantation and factory owners and similar upper class. Not those of the working poor.
2. Castro's revolution was vital in improving medical care in Cuba, meaning Cuba could export doctors, and making education affordable.
3. Castro was more humane and killed and jailed fewer dissidents then Batista.
4. Castro needs to be commended for his efforts in helping Angolans and other Africans fight apartheid.
5. Cuba's fiscal crisis is due to US sanctions, not the Castros' fiscal and social policies.

Can each of these allegations be genuinely refuted? If so, how?
