It's unclear if its rational to be "proud",but I do think it might be rational to be happy about it.

To the extent that people make snap judgments about other people based on race or nationality, it would seem that you'd want people that share your ethnicity or nationality to do well. This likely has a minor increase in people's perception of you.

Likewise, you probably feel shame or unhappiness when the opposite happens. Just look at what being Muslim is like in the US now.

You inspired a related question: is it irrational that I feel proud of the two French people although I'm not French, I just live in France ? Plus, the Vietnamese mathematician has studied and worked in France.

I somehow feel proud that I made a good choice of place to live for now, if that makes any sense.

PS: I noticed they are almost all "outsiders", foreigners that immigrated to Western countries, or locals outside the traditional elite of the Western countries. The point, which is a depressing one, is that mathematics and, more generally, pure science, is an "outsider" activity nowadays.
