Document. History Dept., Holy Cross College ~ "Just War Games" ~ Letter to the editors of COMMONWEAL ~ David writes concerning Peter Steinfels' discussion of just war theory as a response to Gordon Zahn's appeal for a retrospective evaluation of the Vietnam war. O'Brien disagrees with Steinfels' position saying that he does not believe decisions of war should be left up to an international tribunal, and that war can no longer be an instrument of justice. ~ Commonweal ~ 119
