Last Friday, President Trump announced that he was rolling back some of President Barack Obama's changes to America's policy on Cuba. Is the door to Cuba now closed for Americans?

Charles Sennott — Executive Director of The GroundTruth Project — doesn't think so.

"It's really very little change in policy," Sennott explained.

The new policies will make it more difficult for Americans to travel to Cuba purely for tourism, and also ban commerce with businesses owned by the military and intelligence services.But many of the Obama-era policy changes remain intact, including the normalization of relations between the two countries. The new U.S. embassy in Havana, for example, will remain open. 

"This is a theatrical statement of opposition to what President Obama has done," Sennott said. "But where does it really take him?" 

But Sennott believes that, in many respects, the floodgates are already open. Consider the large (and growing) numbers of Americans visiting the island: in 2016, more than 600,000 Americans traveled to Cuba, which was a 34 percent increase over the previous year. 

"I don't think you can stop the momentum of change that's coming with Cuba — just like you can't stop the momentum of the world coming together to address climate change," Sennott said.
