 This involvement is due in large measure to a deliberate policy by the Alfonsín and Menem administrations to get their nation, and its military institutions, involved in this type of extra-Hemispheric UN mission.The Argentine effort also reflects the fact that UN peacekeeping is now part of their formal role statement (Canada takes a similar approach).The Argentine army defines its basic mission, similar to that of most armies, as the defense of state sovereignty by providing a credible deterrent against a hypothetical adversary.
