While many scholars of ethics, philosophy, politics, and social sciences explore the ideas of war and peace, one of the most fundamental questions is whether or not lasting world peace is achievable. On the one hand, the history of politics shows that countries need war to ensure the prosperity of their citizens by acquiring more resources. On the other hand, wars result in significant casualties on both sides of the conflict. Wars also require substantial financial expenditures and, over time, the cost of weapons has grown significantly.
Given that the primary goal of wars is to improve the economic situation and life in the country, continuing wars in modern times appears to be counterproductive. Furthermore, the ideas of human rights and freedoms that have become important to contemporary society contradict the notion of war. In this context, the development of society shifts the priorities of people and governments, making wars unnecessary for prosperity and high well-being. Today, most countries are concerned with internal policies that affect people’s lives. If this trend strengthens in the future, global peace will be achieved eventually.
