Which philosopher indicated that war is fought to achieve peace?

Aristotle is well-known for his philosophical ideas regarding ethics, politics, and the nature of conflict. His perspective on war is often centered around the idea that the ultimate goal of engaging in war is to establish peace and order. This aligns with the concept of "just war theory," which suggests that war can be morally justified if it aims to restore peace and protect the common good.

In Aristotle's view, the pursuit of peace holds a significant moral weight, and engaging in war may be necessary for achieving it under certain circumstances. This foundational belief is a major theme in discussions about the moral justification of war throughout history, making Aristotle's assertion a fundamental concept in political philosophy and military ethics.

The other options present individuals who are notable in their respective fields, but they do not directly embody the philosophical idea that war is fought to achieve peace in the same way Aristotle does. General Jimmy H. Doolittle is celebrated for his leadership during World War II, General Colin Powell is known for his military leadership and the Powell Doctrine, and George MacDonald is recognized more for his literary contributions rather than for treating the philosophy of war and peace.
