A primary role of the State is national defense. However, the data show that Peru has spent little and poorly on national security in recent decades. The composition of the military budget has been inefficient. The budget of the Armed Forces has concentrated on current expenditure, to the detriment of the acquisition and maintenance of equipment and staff training. Much of the weaponry is obsolete. Military pensions and salaries are lagging behind in the region. The structure of the Peruvian military expenditure is anachronistic. A radical redefinition of the national defense policy is urgent.
