Excessive military spending reduces the available financial reserves for health, education, and other human needs. For poor countries, it increases poverty, unemployment, and destitution. It also strengthens dictatorial tendencies in politics and acts against democratic values. If we want to achieve peace, eliminate poverty, decrease inequality, and achieve social justice, we should devote all our energies to reducing military spending and using the released resources for economic development. For that, we need a concerted effort to encourage disarmament.
