There is global consensus that the fall of the Berlin Wall and the dissolution of the Soviet Union marked the end of the cold war. However, the mood with which the end of the cold war was received varied around the world. One response was the attitude of triumphalism commonly identified with Francis Fukuyama’s version of the ‘end of history’. Triumphalists experience the end of the cold war as the victory of the ‘good’ over the ‘evil’ empire. This mood is similar to what the allied forces experienced in the Nuremberg and Tokyo trials after the end of World War II. Both historical moments show how at the end of a war triumphalists exalt their virtues and condemn the principles and actions of the enemy. From a critical point of view, the end of the cold war is a moment for self-criticism, introspection, an opportunity to face our fears and change our mentalities and views about the other. A critical attitude calls for structural reform through introspection and dialogue with the ‘other’. This critical attitude inspired the creation of truth commissions in Argentina (1983), Chile (1990), El Salvador (1992), South Africa (1995), Guatemala (1997), and Peru (2001). In opposition to the arrogant attitudes of triumphalists, truth commissions are institutional initiatives directed at investigating past human rights violations with a focus on restoring dignity to victims. What follows discusses the potential and limitations of truth commissions in questioning the arrogance of US power. Do truth commissions have the potential to challenge U.S. hegemony? Or, on the contrary, are truth commissions another instrument of U.S. human rights imperialism? Is a truth commission for the U.S. possible? Sorting out these questions demands a discussion of the relationship between truth, human rights, and U.S. hegemony. The analysis approaches this task in five ways. First, it examines critically the function of truth commissions in relation to truth and hegemony. An important limitation of truth commissions overlooked by supporters and critics is the nationalist framework within which they operate. The history truth commissions investigate is the national history of human rights violations committed by Argentines against Argentines, Chileans against Chileans, and so forth. The reconciliation sought by truth commissions is national reconciliation. National reconciliation is closing the historical gap that has divided the nation into the warring factions of a civil (domestic, internal) war. However, truth commissions’ nationalist framework reinforces post-cold war triumphalism. By framing human rights violations within the boundaries of the nation, truth commissions end up silencing the responsibility of the United States or other great powers. Second, the chapter analyzes the functions of insincere apologies from such hegemonic states as the US as variation of the triumphalist approach. And third, the paper argues why investigating the direct participation of the United States could help national reconciliation by helping the parties involved to realize that the perceptions of themselves and the other, as well their mutual behavior, was to certain degree conditioned by a third party. Theoretically, understanding that violence is related to global strategic interests, as well as poverty and that poverty is also related to global inequalities could help reconciliation between Peruvians. All the above are reasons why investigating U.S. involvement in human rights violations could help the national reconciliation between Peruvians sought by Peru’s TRC. The reconciliation policy advanced by Peru’s TRC and other similar experiences is predicated on the assumption that such policy will establish the basis of a peaceful society. The theory is that the distancing or alienation between Peruvians is the root of violence; thus, reconciliation is the solution. Is such theory applicable to international relations, that is, to relations between Peruvians and Americans? Addressing this set of questions is the fourth line of inquiry developed in this chapter. By overlooking the direct involvement of the U.S., truth commissions overlook the reconciliation and democracy building in a global context. A strong case could be made that the violence that causes human rights violations around the world could be significantly reduced if the United States engages in multiple processes of international reconciliation. The chapter concludes by taking on the argument for not investigating the direct involvement of the United States: this case is based on the realities of power. The fact that only two truth commission reports mentioned the direct participation of the United States is in itself revealing. One could even speculate whether a truth commission would have been possible if it explicitly announced that one of its purposes was to investigate the direct involvement of U.S. government, corporations, and individuals in human rights violations. Similar to what is said about human rights violations themselves, the problem is not that the truth about direct U.S. involvement is unknown. U.S. direct involvement has been well documented and analyzed in a several studies. The problem is not truth itself, but the extent of public awareness and the political function that such truth could have in changing power relations. In other words, truth commissions are limited by existing power relations, but, at the same time, have the potential of challenging power relations. [ABSTRACT FROM AUTHOR]
