[ WP ] A time traveler has come from the future to cause the death of 4 billion people ... .. in order to save us from something even worse .

`` Well, Mr. President, It's been a year. Do you believe me now?'' 
 
 I stood Looking at the newspaper: June 9, 2015. Next to it, a small moleskin notebook filled with the results of meaningful events hat happened over the last year: Germany winning the world cup against Brazil, Chicago winning the super bowl, 2704 winning lottery combinations from all over the world, all of them right. Formula one results, Election results from Libya, South Africa, Afghanistan, India, Colombia, Brazil and so many others. All of them right. There was no doubt in my mind. This person was a time traveler. 
 
 She posed as a temp on the White House press department. Exactly one year ago, he came into the office to bring me a random paper, and left the notebook on my desk, whispering in my ear: 
 `` I'll return in exactly one year. Have the office empty'' 
 
 The first page had the result of a game between my favorite team and its main rival. It picked my interest. The next pages had all significant events for the year, day by day. The only instruction written on the notebook was never to act on it. I never did. 
 
 So here she was, one year later. The office empty and the secret service camera and mic turned off ( the notebook has instructions for doing that ). 
 
 `` So you are the first time traveler! Wonderful! What is your name?'' 
 `` There's no time for that Mr. President. I know that you have a secret protocol in case you discover a time traveler, but this is more important than that!'' 
 `` What do you mean?'' 
 
 She went towards a wall and plugged some sort of device. All the lights went out. I looked out the Window, Washington was Dark. She was nowhere to be seen. A voice whispered in my ear. 
 
 `` The device was specifically designed for this mission. The secret service will enter in 15 seconds to take you to the bunker, go to the bathroom. I'll be waiting.''

 `` It took ten years to develop the technology for this mission. We had to follow detection protocols, learn how the people of this time operate, plan the possible outcomes. Now Mr. President, I can tell you why. 
 
 In 2148 WW3 will begin. It will not be a nuclear war, there will not be a virus, no zombie apocalypse, none of the scenarios you envision. It will be geological. A technology is being developed that allows crust-level drilling for rare metals. Indochina will weaponize this technology. The us will develop a satellite guided drill that plunges to earth and drills down to the crust effectively creating volcanoes on demand, and everything associated with them. 
 
 In 2162 the first time machine will be complete. 48 hours earlier it will be revealed that the Indochinan government that the US-Canada government have impacted two critical points on earth, effectively generating a resonance of the Earth's mantle. The basically found the planet's reset switch. Everything wiped out. No survivors. I was sent here to prevent that.'' 
 
 `` But how are we supposed to pre..'' 
 
 `` Excuse me sir, but I have to finish before the secret service figure out that their president does n't have indigestion. The only way to prevent WW3 from happening is starting it earlier, with a different technology. The estimated impact of all nuclear bombs in the world is about 4 billion people, half the world's population. The new superpower will be Brazil, and the drilling technology will be delayed for 300 years, according to our estimates. I need you to start WW3 with the US ’ entire nuclear arsenal'' 
 
 `` And what then?'' 
 
 `` I'll be going to Brazil and starting WW4.'' 
 
 `` Are you sure this will work?'' 
 
 `` No. But I am completely sure it's better than the alternative. Here are your targets.'' 
 
 She disappeared again, and I sat inside a bathroom stall, Reading the cities listed in that piece of paper. As I left the bathroom door, holding the piece of paper, I told my chief of staff: 
 
 `` Bring me the black box''
