<span>Diamond is an evolutionary biologist, interested in adaptations, and he proceeds to speculate that New Guineans exhibit these heightened-mental-activity traits in response to their environment, which presents them with constant and varied challenges. He gets away with it because (1) this statement is buried inside his main thesis, which is in accord with the fundamental dogma (Western superiority is just an accident of geography), and (2) his superior racial group is non-white, and it's okay to call whites inferior</span>
Answer:
1775–1830
U.S. Indian policy during the American Revolution was disorganized and largely unsuccessful. At the outbreak of the war, the Continental Congress hastily recruited Indian agents. Charged with securing alliances with Native peoples, these agents failed more often than they succeeded. They faced at least three difficulties. First, they had less experience with Native Americans than did the long-standing Indian agents of the British Empire. Second, although U.S. agents assured Indians that the rebellious colonies would continue to carry on the trade in deerskins and beaver pelts, the disruptions of the war made regular commerce almost impossible. Britain, by contrast, had the commercial power to deliver trade goods on a more regular basis. And third, many Indians associated the rebellious colonies with aggressive white colonists who lived along the frontier. Britain was willing to sacrifice these colonists in the interests of the broader empire (as it had done in the Proclamation of 1763), but for the colonies, visions of empire rested solely on neighboring Indian lands. Unable to secure broad alliances with Indian peoples, U.S. Indian policy during the Revolution remained haphazard, formed by local officials in response to local affairs.
