The clamor for the defense of universal peace is quite old, however, perhaps its greatest expression has been consolidated with the institutionalization of peacekeeping operations (PKO) led by the UN. During the Cold War period, such instruments were little used; however, post-1988, there was a substantial increase in instituted PKOs. This paper presents a reflection on the possible reasons that lead countries to wish to join peace operations. It presents arguments that, more than solidarity, the real interests of states are in recognition by the international community and financing for their regular forces. It seeks to address in detail the Brazilian case, making clear what was the option of Brazilian foreign policy to increase its participation in these operations.
