Answer:
Manifest Destiny was the idea that Americans, that is to say, the United States, had the right to expand to the West, and reach the Pacific Ocean: occupy the lands in between, and spread American values.
It also applies to other parts of the world in a more indirect way, especially Latin America.
The settlement of the West was aided both by economic necessity, because many migrants were arriving in the United States seeking for cheap land, and also by ideology, and the ideology was precisely that of Manifest Destiny.
I think the major reason why American colonists were different is because they came to a new land to flee persecution from their government. In what I have learned about societies forming colonies, many colonies were formed in other countries because a nation had control of that country. Take the Greek empire for example. The Greek citizens moved to counties that Greece had invaded and dwelt among those people and learned from them as well. In the Americas no one had really formed a colony or claimed the land for their country. Hopefully this helps.
They intended to damage the u.s. fleet so badly that by the time it could be rebuit they would have uncontested control of all of asia and the south pacific
I think you are right! i did similar questions and got them right with those answers.
