Ethical systems play a significant role in international relations, as they provide a framework for countries to make decisions and interact with one another. There are several different ethical systems that can be applied to international relations, including consequentialism, deontology, and virtue ethics.

Consequentialism is the idea that the ethical value of an action is determined by its consequences. Under this system, the most ethical action is the one that leads to the greatest overall good or happiness. In international relations, this could mean prioritizing the well-being of the greatest number of people, even if it means sacrificing the interests of some individuals or countries.

Deontology is the idea that certain actions are inherently right or wrong, regardless of their consequences. Under this system, actions that are considered morally correct are those that adhere to universal moral duties or rules. In international relations, this could mean upholding international laws and agreements, even if it is not in a country’s immediate self-interest.

Virtue ethics is the idea that ethical behavior is determined by the virtues that a person possesses. Under this system, a virtuous person is one who exhibits certain character traits, such as honesty, fairness, and compassion, and makes decisions based on these virtues. In international relations, this could mean acting with integrity and treating other countries with respect and empathy.

There are pros and cons to each of these ethical systems, and it is not uncommon for countries to adopt a combination of these approaches when making decisions in international relations. Ultimately, the ethical framework that a country follows will depend on its values and priorities.
