National security is the security of a nation-state, regarded as a duty of government. It includes the nation’s citizens, economy, and institutions. National security is a vital priority in several countries around the world and requires a large budget in order to be built and maintained.

National security requires military and defense spending. In the United States, this includes all regular activities of the Department of Defense, war spending, nuclear weapons spending, international military assistance, and other Pentagon-related spending.

The total world military expenditure was about $1.8 trillion in 2018, a 2.6% increase from 2017. The ten countries with the highest defense spending are:

  1. The United States ($649 billion)
