By definition, the term “Civil War” is a war between citizens of the same country and doesn’t refer to the civility of war. But, sometimes war is necessary.
WW2 is considered to be the single greatest event in world history and cost the US over 400,000 lives. By contrast, the Civil War only involved the US but the cost was over 625,000 American lives. Some studies have suggested that the US would look quite different today if the Union had lost the war. The western states and territories might have seceded and we could have been split up into three or more smaller countries and resembled Europe. Now, you can consider what might have happened to us if we were too weak as a country to fight Germany and Japan simultaneously in WW2. One last thing to worry about. Would the millennials of today fight for our country the way The Greatest Generation did in WW2?
