I wouldn't have slaughtered men, women, and children, for starters--which the English did not allow their own to do.
For extra credit, I might have figured out a way for me and my people to profit from this immense opportunity to trade and grow through an alliance with a vastly more developed culture--which this particular Indian had lived among, educated in the royal court of Spain.
He was clever, and pretended to be a convert to Christianity. He also pretended to be their trusted friend. We say he could read the hand writing on the wall--that this continent was going to be invaded by lots more white Christian men. But actually, he misread it. He was wrong that the Indians had a prayer of keeping Europe out of America--any more than the inhabitants of this continent who preceded the Indians (of whom traces with DNA have been found in the Upper Midwest) had a chance of keeping out this Indian's Asian ancestors.
He had seen enough to realize that his people could prosper from making themselves valuable in this new world that was taking shape.
But no.
So then I assume you’re trying to figure out away for you and your people to profit from the invasion we’re currently experiencing on our southern border.
