Finally, even if some episodes can be considered genocidalthat is, tending toward genocidethey certainly do not justify condemning an entire society. Guilt is personal, and for good reason the Genocide Convention provides that only "persons" can be charged with the crime, probably even ruling out legal proceedings against governments. No less significant is that a massacre like Sand Creek was undertaken by a local volunteer militia and was not the expression of official U.S. policy. No regular U.S. Army unit was ever implicated in a similar atrocity. In the majority of actions, concludes Robert Utley, "the Army shot noncombatants incidentally and accidentally, not purposefully." As for the larger society, even if some elements in the white population, mainly in the West, at times advocated extermination, no official of the U.S. government ever seriously proposed it. Genocide was never American policy, nor was it the result of policy.
The violent collision between whites and America's native population was probably unavoidable. Between 1600 and 1850, a dramatic surge in population led to massive waves of emigration from Europe, and many of the millions who arrived in the New World gradually pushed westward into America's seemingly unlimited space. No doubt, the 19th-century idea of Americas "manifest destiny" was in part a rationalization for acquisitiveness, but the resulting dispossession of the Indians was as unstoppable as other great population movements of the past. The U.S. government could not have prevented the westward movement even if it had wanted to.
In the end, the sad fate of America's Indians represents not a crime but a tragedy, involving an irreconcilable collision of cultures and values. Despite the efforts of well-meaning people in both camps, there existed no good solution to this clash. The Indians were not prepared to give up the nomadic life of the hunter for the sedentary life of the farmer. The new Americans, convinced of their cultural and racial superiority, were unwilling to grant the original inhabitants of the continent the vast preserve of land required by the Indians way of life. The consequence was a conflict in which there were few heroes, but which was far from a simple tale of hapless victims and merciless aggressors. To fling the charge of genocide at an entire society serves neither the interests of the Indians nor those of history.
