Why did Washington seek to protect land that belonged to Native Americans?

Offering Indian tribes a fair price for their land, Washington hoped, would allow the United States to expand with minimal bloodshed and at the same time treat Indian peoples with justice. But when Indians refused to sell, Washington was ready to wage war against them. “Extirpate” was the term he used. Hope this helps!

If he breaks the law then he had to resign from his post and so he'll lose his/her powers.
