Biden takes Cuba off of the state terrorism sponsors list….. a few days before Trump takes office???
As other users in different sites have already pointed out, basically Trump could be able to easily reverse such a decision after he takes office.
Overall, the Cuban gov in response to this policy reversal by making more progress on a deal between the Vatican and themselves to release political prisoners
Now maybe could be some sort of thing that could make the reversal of foreign policy decisions like this a bit more difficult for Trump , but even with that Trump could still make it non-applicable by putting up some extra sanctions and etc.
