You have to have lived at least five consecutive years in the US (two of which after the age 14) in order for your children to be eligible for citizenship. So the guy who lived in Greece is still a citizen (that can't be revoked excepting you renounce it or something), but his kids couldn't apply.
I'd never even considered US citizens who were born outside the country, who then had children without them ever setting foot in America. I didn't know this, but it makes sense.
