do not classify themselves as responsible for the wrongs of their country

Personally, no. But they identify with an entity (a tribe) which they agree is responsible.

Are we talking at the individual level or at the social-group level? At the individual level the phrase "any instance of a large group of people" makes little sense. And at the social-group level personal responsibility isn't relevant, we are talking, I think, about I belong to group X and group X is responsible attitude.
