How many cuban ex-pats do you know? I would say “not many”.
Every cuban ex-pat I know (and thats quite a lot because I live in FL) will tell you there is a Cuba problem. They all still have family suffering under that regime.
Let me rephrase. The is no "Cuba problem" that the US needs to deal with any differently than it deals with/has dealt with the many other countries in the Americas that have/had people suffering under their regimes who had family in the US.
As far as Cuba in particular goes, the suffering there would be a lot less if the US would drop its 65+ year old embargo and let them trade like all the other repressive regimes it is indifferent to.
Most of them don't have a history of direct hostility towards the US and specifically having the willingness to allow a US foe to use their proximity to plant tactical weapons to threaten the US.
Castro was already playing footsie with the Soviets and Castro nationalizing US business interests was one of the reasons we decided to invade.
That was 64 years ago and are you suggesting here that things that happened that far back have no bearing today? Hell, the brother of the dictator from 64 years ago is currently in charge there today still oppressing the Cuban people so it’s not like there hasn't been some continuity.
