How did manifest destiny affect the growth of the nation? what affect did the government’s policies have on the native american nations? could he u. s have reconsidered it’s motivation to expand and considered the effect on native americans?

Well, Manifest destiny meant that the US wanted to control land from the Pacific to the Atlantic, so they wanted most of North America. This meant that they displaced many Native Nations. The US could have reconsidered their motivation but at the time most people had the idea of white supremacy so they did not really care about Natives, and therefore did not reconsider their motivations.
