They vote, they pay taxes, they’re sometimes politically active. From their point of view, they’ve contributed to the success of their country, and they’re proud of it?

Does that work the same way when the country performs its atrocities? Everyone becomes implicit in those crimes because they voted and paid taxes that is used to kill civilians abroad? Or it just applies for “feel good” reasons?

Just because you do what most people do, doesn’t validate being proud of other peoples hard work that actually bring change.

Absolutely correct.
