The article centers on the factors that influenced Peru’s decision to participate in the peacekeeping operations in Haiti, as well as the difficulties it had to face in order to implement that decision. Perhaps the most important influencing factor was the reinsertion of the Peruvian Armed Force in the Western military community after years of struggling against Sendero Luminoso, which had led to serious human rights violations. Other important factors were the aim of achieving prestige and a presence on the international stage, the economic advantages to be gained for the troops, the training benefits, and lastly collaboration with the United States in a mission that was of interest to that country.
