What the Security in the Contemporary World Class 12 Chapter Is About

Security in the Contemporary World is the fifth chapter of Contemporary World Politics. It asks one simple question with a wide answer: what does security really mean? At its core, security is freedom from threats to our core values. The chapter sets out two ways of seeing it.

The whole chapter rests on three big ideas that students must keep in mind:

  • Traditional security: the danger is military attack on the State, answered by force.
  • Non-traditional security: the lens widens to human and global security, covering terrorism, poverty and disease.
  • Cooperation and India: states work together to limit violence, and India uses a four-part strategy.

So the chapter is really about how the idea of security has grown beyond the army and the border. A student who keeps these three threads in mind can connect almost any question in security in the contemporary world class 12 back to one of them. This is why revision works best when you sort each fact under "traditional", "non-traditional" or "cooperation" first.

Traditional Notion of Security

The traditional notion of security is the one most people picture first. In this view the greatest danger to a country is a military threat, and the usual source is another country. To answer questions on it, students must know what it protects and how.

  • The threat: armed attack, from outside the border and sometimes from within.
  • The referent: the State, its sovereignty, independence and territorial integrity.
  • The choices: a threatened government can surrender, deter the attack, or defend itself in war.
  • The tools: deterrence, defence, balance of power and alliance building.

A key exam point is that traditional security treats war as the main danger and the State as the thing to protect. The three choices, surrender, deterrence and defence, are a regular short answer, so learn them as a clear list. Remember that even traditional security accepts rules on war, the old idea of fighting only for a just cause and sparing civilians.

Traditional versus non-traditional security comparison for Class 12 Political Science Chapter 5 Security in the Contemporary World

Non-Traditional Security and New Threats

By itself the military view leaves out a lot. The non-traditional notion widens the lens to human security and global security, where the thing to protect is people and the planet, not just the State. The new threats are a long-answer favourite, so students should learn them as a clear list rather than a story.

New threatWhy it counts as a security issue
TerrorismPolitical violence by non-state groups that targets civilians, often across borders.
Human rightsGenocide and abuse harm people directly; their protection is a global concern.
Global povertyHunger and want kill more people than war and fuel migration and conflict.
Migration and refugeesForced displacement strains states and endangers the displaced themselves.
Health epidemicsDiseases like HIV-AIDS and avian flu spread fast and cross borders.

A sharp point for the exam is that terrorism is a non-traditional threat, because the danger comes from non-state groups and hits ordinary people, not armies. The "human security" question turns on the referent: in non-traditional security the thing protected is the individual, not just the State. Keep that single idea ready and the whole non-traditional section becomes easy to answer.

Balance of Power, Alliances and Cooperation

Inside the traditional view, states use a few classic methods to stay safe without a world government to protect them. These methods are a regular MCQ and short answer, so the table sorts them for fast revision.

MethodWhat it means
Balance of powerA state keeps a careful watch on rivals and builds strength so no neighbour grows too powerful.
Alliance buildingA coalition of states coordinate their forces to deter or defeat a possible attacker, like NATO.
CooperationEven rivals accept limits on war and agree to disarm, control arms or build confidence.

The judgement students should reach is that states rely on balance of power and alliances because there is no world government to keep them safe. A state achieves a balance of power by building its military and economic strength and by forming alliances. Alliances are usually based on national interest and can change when interests change, which is the point examiners want in the "objectives of military alliances" answer.

Disarmament, Arms Control and Confidence Building

The chapter names three forms of cooperation that even rival states accept. Students often confuse them, so learn one clear line for each, because Question 1 is a matching item that tests exactly this.

  • Disarmament: states agree to give up certain kinds of weapons, like the conventions that banned biological and chemical weapons.
  • Arms control: it does not ask states to give up weapons; it regulates how they are made and deployed, like the ABM Treaty and the NPT.
  • Confidence Building Measures (CBMs): a process of exchanging information on defence matters so rivals do not misread each other.
  • Alliance: a coalition of nations that coordinate forces to deter or defeat an attacker.

The trick to the matching question is to separate the terms by their verb. Disarmament is about giving up, arms control is about regulating, CBMs are about talking, and an alliance is about teaming up. Lock the obvious pairs first, then the rest fall into place. This way the four-by-four match becomes quick, safe marks.

India's Security Strategy

The chapter ends with how India tries to stay secure against both military and non-traditional threats. This topic is a regular long answer, so the table keeps India's four components side by side for fast revision.

ComponentKey example to recall
Military strengthWars with Pakistan and China; the 1998 nuclear tests for deterrence.
Norms and institutionsSupport for the UN, non-alignment, the NIEO and UN peacekeeping.
Internal security via democracyLetting communities share power to reduce separatism.
Economic developmentLifting citizens out of poverty so want does not breed conflict.

The honest answer to "which security has India prioritised, traditional or non-traditional" is both. India built military strength and tested nuclear weapons, but it also backed global institutions, internal democracy and economic development. A neat way to remember the four is the word MIDE: Military, Institutions, Democracy, Economic development. Cite one example from each component to score full marks on Question 11.

Security in the Contemporary World Important Questions and Previous Year Trends

CBSE sets a steady mix of MCQ, short and long answers from this chapter. Knowing the pattern helps students decide how much to write. The chapter is a regular source of one 4-mark or 6-mark question, which is why a focused list of security in the contemporary world important questions saves a lot of revision time.

  • Long answer (5 to 6 marks): traditional versus non-traditional security, or India's security strategy.
  • Short answer (4 marks): balance of power, objectives of alliances, or a state's three choices.
  • Source-based: the "Economy of war" cartoon, or a passage on the new threats, with sub-parts.
  • Objective and MCQ: the match item, disarmament versus arms control, and classifying threats.

For quick recall before the exam, students often practise the class 12 political science chapter 5 mcq set and a list of security in the contemporary world class 12 important questions. The most repeated items are the two notions of security and India's four-component strategy, so keep those answer points ready in your own words.

Working through the ncert solutions class 12 political science chapter 5 set twice, once open-book and once from memory, fixes the terms and examples well before the board exam.

Common Mistakes Students Make in This Chapter

A few errors cost marks every year in this chapter. Most come from mixing up the cooperation terms or naming the wrong referent for each notion of security. Avoiding them is the fastest way to lift a score.

  • Confusing disarmament (giving up weapons) with arms control (regulating weapons) - keep them separate.
  • Saying the referent of non-traditional security is the State - it is people and the planet.
  • Calling terrorism a traditional threat - it is non-traditional, by non-state groups against civilians.
  • Writing that the UN controls world security - there is no world government; the UN has only the power members give it.
  • Saying India chose only one type of security - its strategy uses both traditional and non-traditional tools.

Students who fix these five points usually move from average to high marks on the long answers. The exam rewards a balanced view, so always show both notions of security before you judge any threat.
