And then the Serbian was friends with Russia, so Russia declared war on the Austrian. And then once he did that, Germany was friends with Austria, so Germany declared war on Russia. And then Germany was like, I'm sorry, England was like, you can't do that, you know, Russia, so I'm declaring war on you and your mama. And then basically you have World War I. The Great War is what it was called. It was for three or four years, huge trench warfare, hundreds, tens of millions of people dead, something like one-eighth of all French people, men were dead. And basically that war went on for a few years with no end in sight.
