Time Travel Was Not An Option For Truman

The question of the real-world consequences of a choice constrained by particular circumstances is inevitably an empirical one.  The history of warfare is filled with hard choices. I'm not claiming that it's inexorable that any given leader or polity will face a choice as tragic as that which faced Truman in early August 1945.  I'm just saying that we have to evaluate the morality of the choice according to the alternatives that were available without recourse to time travel.
