It does beg the question; If your intention was to be an American, why wait 20 years? It certainly seems as if he held out hope for a "free Cuba" to which he intended to return. More's the pity for his son; Sunk on a technicality.
Exactly, loyalty to ones home country runs deep as was shown during the revolution when children were pitted against parents & husband against wives. That is the entire crux of feudalism, to pit families against each other for the sake of an all powerful government.
This is a critical issue that needs to be resolved. But it will not be settled in the courts, rather it needs to be settled in Congress where the SCOTUS just correctly ruled that according to the US Constitution Congress has full plenary power over all aspects if immigration including that of children born to aliens on US soil. Plenary power of Congress is the only truth of birthright citizenship that Levin has actually spoken the truth on. Thank goodness I have the audio of his words archived & saved through Carbonite.
