🤺Unipolar World

Think of yourself as a student in a class of 40 other students. Amongst, all the students, there one is a student who comes from a strong financial and social background. That student now interferes and controls their other classmate’s work, personal lives and decisions, simply because they are affluent. This is exactly how a unipolar world works, one nation-state acts as a domineering superpower because it has the military power, resources and a strong economy to do so.

Example of Unipolar World

The world became unipolar after the disintegration of the USSR in 1991. The United States then emerged as a sole superpower, with significant economic, military, and cultural influence over other nation-states. Since then, the US has used its influence to promote its interests and values around the world.

Merits and Demerits of a Unipolar World

Following are some merits of a Unipolar World-

  1. In a Unipolar World, a superpower can possibly promote global stability amongst other nation-states without worrying about ideology clash with a competitor. 
  2. The superpower can help promote economic growth and prosperity.
  3. The dominant superpower can promote recognition and acceptance of basic human rights and democracy.

Following are some demerits of a Unipolar World-

  1. Too much power can lead to possible abuse of power.
  2. Lack of accountability.
  3. With the rise of challenger nation-states comes instability and resentment. 

🤼Bipolar World

Consider the example we talked about while defining Unipolar World, a class with one affluent student who controls and influences other students. Now imagine another affluent student joins the class and also exerting control over the class. There is now a division in the class wherein all students side with one or the other affluent student. This is what a Bipolar World looks like, 2 powerful nation-states, both have their own ideology and concept of a perfect world, both compete for power to establish a world order that suits them. 

Example of Bipolar World

A classic example of Bipolar World is ‘The Cold War’. The United States and the Soviet Union were the two dominant superpowers, and they competed for global influence. The US promoted democracy and capitalism, while the Soviet Union promoted communism. The two superpowers engaged in a variety of activities to assert their dominance, including proxy wars, arms races, and propaganda campaigns.

Merits and Demerits of a Bipolar World

The merits of a Bipolar World are as follows-

  1. Both superpowers acts as a counterbalance for each other.
  2. Cooperation between two superpowers can help build a peaceful multilateral world.
  3. If there is competition between superpowers, it can lead to innovation in several fields.
