Traditional Security

1. Introduction

Traditional security refers to the conventional understanding of security in which the state is the primary object of protection and military threats are regarded as the principal sources of insecurity.

For much of modern international relations, security was understood primarily in terms of territorial integrity, political independence, military capability, and survival of the state. States developed armed forces, alliances, deterrent capabilities, intelligence systems and defence strategies largely to protect themselves against external military threats.

Traditional security remains an important foundation of international relations. However, the concept has expanded significantly because states and societies also face economic, environmental, technological, health, demographic and other forms of insecurity.

2. Meaning of Traditional Security

Traditional security is the protection of the state from external military threats and challenges to its sovereignty, territorial integrity and political independence.

Its central question is:

How can a state protect itself against threats, particularly military threats, posed by other states?

The traditional approach therefore places considerable emphasis on:

1. Military power
2. Territorial defence
3. National sovereignty
4. Strategic deterrence
5. Alliances
6. Balance of power
7. Intelligence
8. Defence preparedness
9. War and peace
10. Survival of the state

3. State as the Primary Referent

The traditional security approach treats the state as the primary referent object of security.

The state is considered vulnerable because another state may:

• invade its territory
• attack its population
• overthrow its government
• destroy its military capability
• occupy strategic territory
• threaten its sovereignty
• impose unacceptable political demands through force

Consequently, national security is closely associated with state survival.

4. Military Threats

Military threats occupy the central position in traditional security thinking.

A military threat may involve:

• invasion
• armed attack
• border conflict
• military coercion
• naval blockade
• air attack
• missile strikes
• military occupation
• insurgency supported by another state
• nuclear threats

Military capabilities therefore become important indicators of a state’s ability to defend itself.

5. Territorial Integrity

Territorial integrity means protecting the geographical territory of the state from external violation.

Borders have traditionally been regarded as fundamental elements of national security. A state may therefore consider:

• border defence
• territorial surveillance
• strategic depth
• border infrastructure
• military deployment
• airspace protection
• maritime security

as important components of national security.

6. Political Independence

Traditional security also seeks to protect the state’s ability to make its own political decisions.

External military pressure can undermine political independence even without formal occupation.

For example, a powerful state may threaten military action to influence another state’s foreign policy. The threatened state may remain legally sovereign but experience significant limitations on its freedom of action.

7. National Sovereignty

Sovereignty is closely connected with traditional security.

A sovereign state possesses authority over its territory and population and maintains independence from external control.

Military threats can challenge sovereignty directly through:

• invasion
• occupation
• intervention
• coercion
• support for armed groups
• violation of territorial waters or airspace

8. Self-Help and National Defence

The international system lacks a world government with a universal monopoly over legitimate force.

From a traditional security perspective, states therefore cannot depend entirely on others for survival.

They must develop their own defensive capabilities.

This is associated with the principle of self-help, particularly prominent in realist theories of international relations.

States may strengthen security through:

• larger armed forces
• advanced weapons
• military technology
• intelligence capabilities
• strategic partnerships
• alliances
• defence industries

9. Balance of Power

Traditional security is strongly associated with balance-of-power politics.

If one state becomes significantly more powerful, other states may respond by:

• increasing their military capabilities
• forming alliances
• strengthening existing partnerships
• developing strategic weapons
• improving intelligence cooperation

The objective is to prevent excessive concentration of power.

10. Alliances

Alliances are important instruments of traditional security.

An alliance involves cooperation between states for common strategic or security purposes.

Examples from modern international history include:

• NATO
• Warsaw Pact
• military alliances during the First World War
• military partnerships developed during the Cold War

Alliances can increase deterrence by making potential aggression more costly.

11. Deterrence

Deterrence seeks to prevent an adversary from taking an unwanted action by convincing it that the costs will outweigh the benefits.

Traditional deterrence may depend upon:

• conventional military superiority
• retaliatory capability
• nuclear weapons
• credible military commitments
• alliance guarantees

Nuclear deterrence became particularly important during the Cold War.

12. Security Dilemma

Traditional security can produce a security dilemma.

When one state increases its military capability for defensive purposes, another state may interpret that increase as threatening.

The second state responds by increasing its own military capability.

This can create a cycle of:

Defence → suspicion → military buildup → counter-buildup → greater insecurity

Thus, measures intended to increase security can sometimes produce insecurity.

13. Arms Competition

Traditional security frequently generates arms competition.

States may compete over:

• fighter aircraft
• missiles
• naval forces
• tanks
• military technology
• nuclear weapons
• missile defence
• space capabilities

Arms competition can increase national military capability while simultaneously increasing regional or international tensions.

14. Intelligence and Strategic Information

Security is not based solely on weapons.

States also require intelligence concerning:

• military capabilities of other states
• troop movements
• strategic intentions
• defence technologies
• military alliances
• potential threats

Intelligence therefore supports strategic planning, deterrence and defence preparedness.

15. Conventional and Nuclear Security

Traditional security includes both conventional and nuclear dimensions.

Conventional security involves weapons such as:

• aircraft
• artillery
• armoured vehicles
• ships
• conventional missiles
• small arms

Nuclear security involves:

• nuclear deterrence
• nuclear arsenals
• nuclear doctrines
• command and control
• arms control
• non-proliferation

The existence of nuclear weapons fundamentally transformed traditional security calculations.

16. Traditional Security During the Cold War

The Cold War represented a major period of traditional security politics.

The United States and Soviet Union competed through:

• military alliances
• nuclear arsenals
• conventional forces
• ideological competition
• proxy conflicts
• intelligence operations
• technological competition

The possibility of nuclear war made deterrence and strategic stability central concerns.

17. Traditional Security and War

Traditional security studies frequently examine the causes, conduct and consequences of interstate war.

Important questions include:

1. Why do states go to war?
2. How can war be prevented?
3. How can military power influence diplomacy?
4. What makes deterrence credible?
5. How should states respond to threats?
6. How can strategic stability be maintained?

18. Traditional Security and Realism

Traditional security thinking has strong connections with realism.

Realist scholars generally emphasize:

• anarchy
• state survival
• power
• national interest
• military capabilities
• self-help
• competition

Realism does not necessarily argue that war is inevitable. Rather, it emphasizes the structural conditions that make security competition a persistent feature of international politics.

19. Criticism of Traditional Security

Traditional security has been criticized for focusing too narrowly on military threats.

Critics argue that people and states can also be threatened by:

• poverty
• pandemics
• climate change
• food insecurity
• water shortages
• cyberattacks
• organized crime
• economic crises
• forced migration

These concerns contributed to the development of broader approaches to security.

20. Traditional Security versus Human Security

The difference can be summarized as follows:

Neither approach completely eliminates the importance of the other. A state can face conventional military threats while simultaneously experiencing non-military insecurities.

21. Contemporary Relevance

Traditional security remains relevant despite the expansion of the security agenda.

States continue to invest heavily in:

• armed forces
• border security
• missile systems
• intelligence
• military technology
• nuclear deterrence
• strategic partnerships

At the same time, traditional military security increasingly overlaps with cyber, economic, technological and environmental security.

22. Changing Nature of Traditional Security

Modern military competition increasingly involves:

• precision weapons
• drones
• artificial intelligence
• cyber operations
• electronic warfare
• satellite systems
• autonomous systems
• information operations

The traditional objective of state survival therefore remains, but the instruments of security are changing.

23. Importance for International Relations

Traditional security provides the foundation for understanding:

• war
• peace
• alliances
• deterrence
• arms races
• strategic stability
• military strategy
• balance of power
• great-power competition

It remains essential for understanding the behaviour of states in an anarchic international system.

24. Conclusion

Traditional security is the classical state-centered approach to international security. It focuses primarily on protecting sovereignty, territorial integrity, political independence and state survival against military threats.

Although contemporary security studies have expanded beyond military concerns, traditional security remains fundamental because states continue to confront armed conflict, military competition, nuclear deterrence and strategic rivalry.
