Do nations engage only in just wars, defending itself against aggressive opponents and protecting it

What Are the Causes? Wars in our time are civilian wars.
What fuels the fires of such cruel wars are Ethnic and tribal hatred, religious differences, injustice, and political turmoil are all significant factors. Another root cause is greed—greed for power and greed for money. Political leaders, often motivated by greed, stir up the hatred that fuels the fighting. War is never justified even against one's enemy because it is ordinary the people, men, women and children who suffer. The bible promised that very soon wars will be abolished. Lasting peace can never be established while people are learning to kill. Many centuries ago, the prophet Isaiah wrote: “If only you would actually pay attention to [God’s] commandments! Then your peace would become just like a river.” (Isaiah 48:17, 18) When people acquire accurate knowledge about God’s Word and learn to love God’s law, violence and war become repulsive to them.
