National Security

… a core concept in Global Context and Atlas105

Concept description

Wikipedia defines national security as the security of a nation state, including its citizens, economy, and institutions, and is regarded as a duty of government.

Wikipedia elaborates:

“Originally conceived as protection against military attack, national security is now widely understood to include non-military dimensions, including the security from terrorism, crime, economic security, energy security, environmental security, food security, cyber security etc. Similarly, national security risks include, in addition to the actions of other nation states, action by violent non-state actors, narcotic cartels, and 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 enforce national security. 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.”

To see how one middle-power government represents the principal elements of national security, it is interesting to view the Government of Canada’s webpage on national security. On 11 May 2019, the page lists:
