If yes: give them the choice. Seeing the number of arguments, it seems the best thing to do: even if the SC refuses it, there are options to become a citizen later using lottery, H1B or simply employment by one of the multitude of global corporations (there are bound to be more later). Borders will become less important over time.
Ultimately, Europe is probably the best bet in this case. The US sounds nice, and is a nice country to travel around, but living there is harsh and not very welcoming (little assistance if you go unemployed e.g.). Go for the safest choice for now : let them make the choice later.
