National security
National security, or national defence (national defense in American English), is the security and defence of a sovereign state, including its citizens, economy, and institutions, which is regarded as a duty of government. Originally conceived as protection against military attack, national security is widely understood to include also non-military dimensions, such as the security from terrorism, minimization of crime, economic security, energy security, environmental security, food security, and cyber-security. Similarly, national security risks include, in addition to the actions of other states, action by violent non-state actors, by narcotic cartels, organized crime, by multinational corporations, and also the effects of natural disasters.
Governments rely on a range of measures, including political, economic, and military power, as well as diplomacy, to safeguard the security of a state. They may also act to build the conditions of security regionally and internationally by reducing transnational causes of insecurity, such as climate change, economic inequality, political exclusion, and nuclear proliferation.
The concept of national security remains ambiguous, having evolved from simpler definitions which emphasised freedom from military threat and from political coercion. Among the many definitions proposed to date are the following, which show how the concept has evolved to encompass non-military concerns:
Potential causes of national insecurity include actions by other states (e.g. military or cyber attack), violent non-state actors (e.g. terrorist attack), organised criminal groups such as narcotic cartels, and also the effects of natural disasters (e.g. flooding, earthquakes). Systemic drivers of insecurity, which may be transnational, include climate change, economic inequality and marginalisation, political exclusion, and nuclear proliferation.
In view of the wide range of risks, the security of a state has several dimensions, including economic security, energy security, physical security, environmental security, food security, border security, and cyber security. These dimensions correlate closely with elements of national power.
Increasingly, governments organise their security policies into a national security strategy (NSS); as of 2017, Spain, Sweden, the United Kingdom, and the United States are among the states to have done so. Some states also appoint a National Security Council and/or a National Security Advisor which is an executive government agency, it feeds the head of the state on topics concerning national security and strategic interest. The national security council/advisor strategies long term, short term, contingency national security plans. India holds one such system in current, which was established on 19 November 1998.
Although states differ in their approach, various forms of coercive power predominate, particularly military capabilities. The scope of these capabilities has developed. Traditionally, military capabilities were mainly land- or sea-based, and in smaller countries, they still are. Elsewhere, the domains of potential warfare now include the air, space, cyberspace, and psychological operations. Military capabilities designed for these domains may be used for national security, or equally for offensive purposes, for example to conquer and annex territory and resources.
In practice, national security is associated primarily with managing physical threats and with the military capabilities used for doing so. That is, national security is often understood as the capacity of a nation to mobilise military forces to guarantee its borders and to deter or successfully defend against physical threats including military aggression and attacks by non-state actors, such as terrorism. Most states, such as South Africa and Sweden, configure their military forces mainly for territorial defence; others, such as France, Russia, the UK and the US, invest in higher-cost expeditionary capabilities, which allow their armed forces to project power and sustain military operations abroad.
