Q.'Balance of power' requires countries to __________. (A) give up certain kinds of weapons (B) regulate acquisition and development of weapons (C) coordinate their actions to defend against military attack (D) maintain a favourable balance with other countries

Let’s start with something you already know. Think of a seesaw in a playground. If two children of roughly equal weight sit on opposite ends, the seesaw stays level — neither side can simply slam the other to the ground. But if a heavy adult sits on one side, the child on the other end is stuck in the air, helpless. The seesaw works only when both sides have enough weight to check each other.

That is the core intuition behind Balance of Power in international relations. It is the idea that peace and stability are most likely when no single country or group is so powerful that it can dominate all others. Instead, power is distributed in such a way that any one actor who tries to push too far will be met by a combination of others strong enough to push back.

The precise meaning

In the NCERT Class 12 Political Science textbook (Chapter 1, The Cold War Era), Balance of Power is described as a situation in which no one nation or alliance is so powerful that it can threaten the security of others. It is not about everyone being equally strong — that is impossible. It is about a rough equilibrium, where the cost of aggression becomes too high for any would‑be bully.

The textbook explains that during the Cold War, the world saw a classic example: the United States and the Soviet Union were the two superpowers. Each had a huge arsenal of nuclear weapons and a network of allies. Neither could defeat the other without suffering unacceptable damage. That mutual fear — not goodwill — kept the peace between them for decades. This is Balance of Power working at the global level.

Why does it matter?

Balance of Power is not a law of nature; it is a strategy that countries deliberately pursue. Here is why it matters:

• It prevents one country from becoming a hegemon — a single power that can dictate terms to everyone else. History shows that when one state becomes overwhelmingly strong, it tends to bully its neighbours, and war becomes more likely.
• It creates a system of deterrence. If you know that attacking another country will bring in its allies against you, you think twice. This is why countries form alliances (like NATO during the Cold War) — to pool their strength and make the balance tilt against an aggressor.
• It gives smaller countries room to survive. A small nation can stay independent not because it is strong, but because the big powers are too busy checking each other to swallow it up. This is called the security dilemma in reverse: the very rivalry of the strong protects the weak.

How do countries maintain a balance?

Countries use several tools to keep the balance from tipping:

• Alliances — binding agreements to come to each other’s aid if attacked. Example: the North Atlantic Treaty Organization (NATO) or the Warsaw Pact.
• Armaments — building up one’s own military strength so that an adversary cannot easily win.
• Buffer states — keeping a neutral country between two rivals so they do not share a direct border (e.g., Afghanistan between the British and Russian empires in the 19th century).
• Divide and rule — a powerful country may deliberately keep its rivals weak by preventing them from uniting against it.

A common misunderstanding

Many students think Balance of Power means “everyone has the same amount of military force.” That is not true. The United States today has a military budget larger than the next ten countries combined. Yet the world is not in a state of pure American domination. Why? Because power is not just military — it is also economic, diplomatic, and technological. China, the European Union, Russia, and India each have different kinds of strength that check the US in different ways. The balance is complex and multidimensional.

In a nutshell

Balance of Power is the international equivalent of the seesaw principle: when power is roughly balanced, no one can push the other off. It is the reason the Cold War stayed cold, and it remains a central idea in how countries think about security, alliances, and war. The NCERT textbook treats it as one of the key concepts for understanding the Cold War era — and it is just as relevant today, whether we are talking about the rise of China, the role of NATO, or the nuclear standoff between India and Pakistan.
