Rebellion in Cuba and Venezuela?

Rut Diamint and Laura Tedesco have an essay in Foreign Affairs about Cuba, arguing that the long-standing revolutionary model is ending and that we don't know what will replace it. There is one part that I wonder about:

To be sure, many Cubans would likely perceive their government’s acquiescence to U.S. demands as an erosion of Cuban sovereignty, even a reversion to the island’s pre-revolutionary status as a U.S. client state. A rebellion by the military and parts of society cannot be ruled out.

Is this true? In both Venezuela and Cuba we have a strong revolutionary past that has long ceased serving its own citizens. Further, the people in power aren't the original leaders, who had strong personal followings. Instead, there are annointed leaders who mostly make their citizens' lives worse. These revolutions are long dead.

I am dubious about the "reversion" argument because it's over 60 years ago so very few people experienced it. I can see military leadership feeling threatened (as targets) but would rank-and-file Cubans want to fight for this revolution? What would the goal of such a rebellion be? Put some authoritarian technocrat back in power?

Nationalism matters. A lot. U.S. protectionism will wear thin, perhaps quickly. But people want solutions to immediate problems. The Venezuelan revolution was starting to fail before the U.S. government turned the economy screws on it. The Cuba revolution had suffered the embargo for many years but is a dependent revolution so was hurt even worse by the fall of the Soviet Union and the gradual decline of Venezuelan oil production. Obviously the Trump administration made things worse but they were already bad.

Venezuelans and Cubans will certainly fight for their countries but I am not convinced they'll fight for these governments. I especially wonder because up to this point Trump has avoided occupying forces that could become targets. An occupying force would change everything but that's not where we are up to this point.
