2. Morgenthau’s Six Principles of Political Realism
Morgenthau summarized his theory in six guiding principles:
1. Politics is governed by objective laws rooted in human nature.
o Human beings are driven by a desire for power, and this shapes politics.
2. Interest defined in terms of power.
o States act based on national interest, and that interest is always linked to
power.
3. Power is universal but context-specific.
o Power can mean military strength, economic influence, or even diplomacy,
depending on the situation.
4. Morality is important but secondary.
o Leaders may use moral language, but decisions are ultimately about power
and survival.
5. No universal moral laws apply equally to states.
o What may be moral for individuals doesn’t necessarily apply to states in
international politics.
6. Politics is autonomous.
o International politics must be studied separately from economics, law, or
religion, because it has its own logic—power.
3. Why Morgenthau’s Theory Was Influential
• Post-World War II Context: After two world wars, many thinkers realized that
idealistic approaches (like relying on international law or organizations alone) were
not enough. Morgenthau’s realism explained why conflicts kept happening.
• Practical Guidance: His theory gave policymakers a framework: focus on national
interest and power, not just lofty ideals.
• Foundation for IR Studies: Realism became the dominant school of thought in
international relations for decades.
4. Criticisms of Morgenthau’s Realism
While Morgenthau’s ideas were groundbreaking, they faced strong criticism over time.
a) Overemphasis on Power
Critics argue that Morgenthau reduces everything to power. But international politics also
involves cooperation, institutions, and shared values. For example, organizations like the UN
or treaties on climate change show that states can work together beyond pure power
struggles.
b) Neglect of Economics and Globalization
Morgenthau focused heavily on military and political power. But in today’s world, economic
interdependence, trade, and globalization are equally important. A country’s strength is not
just about armies—it’s also about technology, markets, and innovation.
