whats going on?

i was just thinking to my self in history class, thinking maybe the world is going to war, from all the conflict of India and North Korea testing their nukes, and the war with Iraq and Afganistan. Maybe this is all linked together to make this one giant fued with politics that its going to be another world war. I’m also trying to think what this would be like, Nucular holocaust or just like what has been going on but more severe, anyone who reads this maybe be shocked but since no one does i leave this to you, the world might be at the brink of war and you dont know it!
