Is this the outcome of tribalism and jingoism?

A short excerpt from a futuristic novel series, "The Expanse", by James S.A. Corey, "Persepolis Rising", copyright 2017, Book 7 of 9:

Singh speaking, “The sad fact of the human species that High Consul Duarte understood so well was that you could never overcome tribalism and jingoism with an argument. Tribalism was an irrational position, and it was impossible to defeat an irrational position with a rational argument. And so, instead of presenting a logical plan for why humanity needed to give up the old national and cultural divides and become a single unified species, he obeyed the old forms that everyone would understand, and went to war.”
