National Security

Every nation defends itself. Most governments, in fact, regard national security as their highest concern. From military readiness to foreign policy and domestic laws, governments devote vast resources to protecting their nations in many ways. This fundamental responsibility never changes, but how it is defined by a government and its people can vary dramatically over time. Political, cultural and social forces, occurring within a nation itself and on the world stage, all work to shape the definition of what makes it secure. Constitutional law tells governments broadly what they can and cannot do in the name of security. Whether in peacetime or in war, the Constitution imposes stability and limits upon official power.
