World War I
"Only the dead have seen the end of war."- Plato
World War I has been largely debated on the true cause of it. The breakdown of it is essentially that countries came together to form "super alliances."
Middle school scenario: You are enjoying recess when someone comes up to you and pushes you. Now you have a conflict. "Why did you push me, bro?" Your new enemy responds by stating that he thinks your kickball team sucks and that you don't deserve to play.
Now the rest of your classmates notice your scuffle. People around you debate on which side to take. Yours? or Jeffery's. I feel like Jeffery is a solid enemy name. Some join Jeffery, and some join yours. Now the fight has more than two people involved
World War I was definitely a much bigger issue than a middle school kickball scuffle during recess. If you had watched the video above, you now know that there was an assassination of a high official which made a ton of people super angry.
