104. Stateless Nation

A stateless nation is a group of people with a common identity who do not have a territory considered to be a sovereign state. These nations often strive for national self-determination.

The Kurds are an example of a stateless nation, with a distinct cultural identity but no official state of their own.

106. Territorial Integrity

Territorial integrity refers to the principle that the defined territory of a state is inviolable and must be respected by other states. This concept is fundamental in international law and relations, ensuring that national borders are not violated or altered without lawful and mutual agreement.

Upholding territorial integrity is crucial for maintaining international peace and stability.

107. Totalitarianism

Totalitarianism is a political system where the state holds total authority over society and seeks to control all aspects of public and private life. In such regimes, political power is often held by a single party or leader, and there is little or no tolerance for political dissent.

George Orwell’s novel ‘1984’ depicts a dystopian society under totalitarianism, where the government exerts complete control over its citizens.

108. Transnational Issues

Transnational Issues are problems that transcend national borders and require a collective approach to solve. These include global challenges such as climate change, terrorism, pandemics and international crime.
