At the time of settlement in the early 1600's, the east coast had been decimated by the plague and was an unihabited waste. That is how the Pilgrims were able to settle into a ready made village devoid of inhabitants.
For the most part in the rest of the country, the transfer of sovereignty was done by treaty and purchase, and not war. That's why there are all these Indian Casinos and Indian hunting privileges.
if you choose to forget the French and Indian War, Pontiac’s War ,etc., etc. Go ahead. Don’t expect others to go along with your lies.
