The theories on what it takes to make a successful revolution. DeFronzo’s factors are a very interesting way of quantifying the steps needed (though it seems to only apply to popular revolutions).
A definition of reform versus revolution. I found the definition we used interesting because it focused on goals rather than means: you could theoretically have a revolutionary movement through constitutionalist means. I’m not sure of its usefulness in practice, as it is at odds with other more common definitions. It is something to think about though.
Not to completely trust the OAS. With our analysis of the Cuban Revolution, and my own work with researching the coup in Bolivia, the credibility of the organization has been shaken for me. Even more generally, I’ve learned to be a lot more skeptical of graphs and charts, looking at what information they leave in and what they leave out. The OAS’s charts on Venezuela seemed nice and accurate, but it was still a good mindset to be wary about the organization’s motive. No data is free of bias.
