Too many people have somehow gotten it into their heads the laws of the US apply to every other country, and they don’t.
IIRC the US is one of the few if not the only country in the world that makes you a citizen simply by being born in the country.
Just like some countries don’t recognize a woman as having the right to pass citizenship to the child only the father does. In that case the mother not being an American citizen would make no difference since by the laws of her country she couldn’t pass citizenship to the child.
So saying a person is or isn’t a NBC isn’t as open and closed as everyone thinks it is.
It depends on the laws of the other country as to whether or not the child is a citizen of the country.
His father being from Cuba was more than likely stateless at the time so he couldn’t pass Cuban citizenship.
If Canada doesn’t make you a citizen simply by being born in the country, then his citizenship would fall to his mother only.
This class of citizenship avoids all legal rights and claims of, by and for that child by any other nation and, to some extent, nationality.
Born in country to citizen parents is the gold standard for undiluted citizenship and would naturally be what the FFs would want for the single person granted essentially one third of the government's power and control of the military.
They were practical and loyal to what they were creating here. No way they'd go with any lesser standard for the highest office.
Canada does grant citizenship based on birth. A friend I grew up with was born in Montreal because her US parents were working there that year. Not only does she have a Canadian as well as a US passport, but her children, who have never been to Canada have Canadian passports.
