Historically, conquest of nations has made conquerors rich through plunder, access to new resources and enlarged trade by controlling a conquered nations' economy. In today's complex system of international trade, characterised by multi-national agreements, mutual inter-dependence and availability of natural resources etc., the freedom to exercise choice of policies to develop a nation's economy in the manner desired, invites economic security. Economic security today forms, arguably, as important a part of national security as military security. The creation and protection of jobs that supply defense and non-defense needs are vital to national security. Developing countries are less secure due to lack of employment for their citizens.
