Across the majority of the world, there have been empires on each continent except what we know today as the USA. Why is that? Why did the Native Americans not create an empire similar to other cultures? Here are some suggestions: 1) The religion of the Native Americans did not allow them to exploit the land as per the necessary resources of an empire. 2) The resources needed were not available. 3) They did not have the technology to make use of the resources if they were available. 4) Among the several hundred tribes, one was not able to gain dominance over the other to create an empire. 5) Their detachment from the rest of the world kept them away from international invasions (which reduced the need for a progressive advancement in weaponry and other defensive measures), ideas, etc. Agree or disagree?
