Last I checked, those countries were in the 'Americas'. North, Central and South America - the people who lived there are collectively, American Indians.
Here I must also disagree with you. Not all NA cultures were 'warrior' cultures. One doesn't think of the Ojibwa in the same way one thinks of the Comanche.
Just because 'One' does not think, doesn't mean that it isn't so - the Ojibwa were warriors you just missed the movie about them.
No one ever thought of the Dine' as warriors either. Beware the 'Hollywood Indian' . I mean no disrespect but do look up up the Ojibwa, you will be surprised. Many eastern and far western tribes were killed off/civilized early on so the popular history has passed most people by, the west tribes like the Comache you mentioned were documented with photos and many retain much of their history.
