If you read the Universal Declaration of Human Rights, the right to citizenship (a nationality in the terms of the document) is already recognized by every country, including the United States. So is the right to request asylum and have a timely hearing regarding that request, the right to move freely within the borders of any state, to leave your home country and to return to it if you choose, etc. What’s a hard sell is getting countries to implement these rights.
Again, rights have nothing to do with how many countries recognize them or whether or not they are a hard sell. People don’t stop having rights just because others don’t want to recognize them. My article wasn’t about how difficult it is to convince some people, or even most people, that an infant who is completely innocent and lacking any control over their situation shouldn’t be tossed out of a country and forced to endure poverty or persecution just because the country isn’t happy with its parents for some reason. You speak of a country’s right to self-determination without any regard for the infant’s. Why not allow it to remain until adulthood and then request it choose between in his/her parent’s country and the one it was born in? That, at least, would acknowledge the reality that it didn’t choose where it was born but, as an adult, can make a choice as to where he/she is going to live.
