Sadly, I think the answer is yes. Iran might put a brief damper / brake on the timeline but the current US administration seems intent on seizing the moment and pushing out the Castro government once and for all. It's "beef" that goes a long way back, if you look up the history of Cuba, even how Fidel Castro first came to power was under the banner of pushing out that era's US-backed administration. And Cuba had been a point of major US economic interests as well so the USA was not happy to see the rise of the Communists in their backyard.

EDIT: you mentioned you're a non-American and the Americans you talk to are all upset/disappointed. If you're European especially, the Americans you're most likely to interact with are well-educated and liberal. There are parts of the country that are firmly pro-Trump, where it's completely out of the norm to have liberal / European-style values.
