How to get translated list of all country names in dotnet

Question

I'm trying to build a dictionary of country names with their two character country code, but with the country name translated to a selected language.

I know the country code for the United Arab Emirates is AE, but what would I pass to an IStringLocalizer to get it translated?

Could I use something like the following?

var localizer = _localizer.WithCulture(new CultureInfo("fr-FR"));
var countryNameTranslated = localizer[103392].ToString();

But what I need is the complete list of two character country codes and their (ISO?) numbers, so I can iterate through all of them, using a selected culture code and the localizer to translate them all.

How do I get the complete list of 2 character codes and their numeric codes from the dotnet core Microsoft libraries? (Is this even possible?)
