Answer:
Justifiable policy to them, national disaster now
Step-by-step explanation:
Back then they thought of Native Americans as barbaric. Most had no moral objections to kicking them off of their lands and deporting them further and further west, and many did believe in Manifest Destiny. Now most look at Manifest Destiny as a period where Native culture was destroyed, and many are still mad at the governments actions back then. But you must take into account that Manifest Destiny made America the powerhouse that it is today.
