Havana’s prisoner release demonstrates to the international community at large its willingness to compromise and desire to reduce conflict with Washington. It puts the United States government on record acknowledging that Cuba is not a state sponsor of terrorism. And it puts the Trump administration in the awkward position of having to choose between leaving the new measures in place or reneging on an agreement to release 553 people from jail.
Obamna did the same thing, if Biden really cared he would have done it at the start of his term instead of the end.
And what’s to stop Trump from re-re-designating Cuba tomorrow? Nothing. Such wankery.
