[ WP ] You are a time travelling agent , and you need to stop a nuclear war without killing anyone .

The computer whizzed through its computations. Hayden worked on his documents that needed to be completed before any adjustment was made. He hated this part of the job but in a certain sense this was the only time he'd ever need to do this. Hayden was an adjuster. His job involved searching through the annals of history for small'butterflies', as they were called, to step on. He would be the one to go back and institute a change such that the ripples in local history would eventually grow to a tsunami of centuries. This was the most important job of his life, as this was the biggest change he'd ever made and will ever make. 
 
 Hayden studied several computations on the computer as they flew threw the quantum fluctuations. So many variables only a quantum computer could handle it. His superior, Taggart, stepped in. 
 
 `` Has the computer located the necessary changes?'' 
 
 The Computer clicked off as the final sum completed and the list was displayed on the monitor. 
 
 `` Perfect timing again Taggart. Looks like...'' Hayden studied the monitor `` June 6th 1994.'' Taggart eyed the report `` The necessary change looks to be smashing in a car window.'' 
 
 Hayden took the portable display monitor and headed for the door. Taggart spoke up, `` Be careful on this one Hayden, this is a major change. Humanity dies because of this one.'' 
 
 Hayden entered into the chamber. He clicked on the elevator style machine as it took him'down'. He felt a similar sensation to going down on an elevator. The slight weightless you feel in your stomach, except this was temporal so he felt his temporal weight lessen as he was allowed down-when. He stepped out of the elevator. There stood the 1990's crew of the temporal agency. 
 
 For each decade a crew is assigned, who each report to a century supervisor, who in turn reports to the millennial coordinator, who finally reports to the bureau. He was an adjuster so he moved about the millenniums making the needed adjustments. Usually time would take its course and any single change could affect only local time. The larger the change the higher up the needed support. This change would need all 7 of the bureau's approval, which he had. 
 
 He could see it now, as he stepped out of the elevator. He would exit at January 1st 1994, each door would lead out to that day. He needed to wait 6 months and 5 days. Then he would smash in the driver-side window of a new 1994 Honda Accord Ex, parked at 1903 far barrow lane. Hayden walked through the office. It was styled after 1994 decor should any normal human accidentally walk in to the lobby. He passed by the people working on small minor adjustments. A kid being stopped on his bike by a cop ( in reality a temporal agent ), preventing the death of the child and the subsequent depression of the mother who would then never be able to run for a school board office making a pivotal local change that was needed for local educations. But all of those were incredibly minor. No real change would result from those. The weight of his change would ripple through millennium. 
 
 Hayden stepped out on a sunny lawn in Austin Texas January 1st, 1994 in front of The Temporal Bureau. He looked at the file he held. A picture of the ancient ruins of Austin Texas dated January 1st, 5684. Several months prior among the millions of change requests that were constantly being checked and adjusted and checked again. The right combination of changes, which would be researched to prevent this kind of thing from happening again, would build up and eventually cause the nuclear holocaust of the human race, but now Adjuster Hayden would, on June 6th, smash a car window preventing the death of all mankind. 
 
 He lived for the next 6 months in an apartment just outside of Austin, working at a grocery store. It was a hot summer day June 6th, he drove up and parked his car in an alley way near by. He took out his crowbar and tried to nonchalantly walk up to the accord. His watch beeped. 10:24 am. Right now the owner would be in the bathroom not able to hear a crash outside. He would then be late for work because of the realization of what happened. Because of that he would lose his job. And he would never make a contribution to the company that in 54 more years would become a multi-billion dollar company. He never had a higher up position so he would never write a paper proposing a certain deal with another large conglomerate that would thus never go through. His contributions would never lead to one of the biggest conglomerates in human history entering into an arms race which would stifle human progress to the stars. That pause would eventually lead to several superpowers not having the room to expand themselves and would lead to in 3 thousand years a war, which would cause the stockpiling of nuclear warheads which 2 thousand years later would end all human life. 
 
 Hayden stepped back into the Temporal Bureau building. Taggert was waiting for him. Several guards grabbed him. Taggert looked at him harshly and read off of a portable screen `` You have been found guilty of making an unauthorized adjustment. You will be tried by the Bureau heads.'' Hayden looked in shock as he was dragged away by the guards. 
 
 Later in his cell, he sat in the cold. All changes are supposed to be kept in files outside of time to prevent this sort of thing from happening. A knock was heard and the door opened. A man Hayden had never seen before stepped in. A small gold pin he wore told Hayden who he was. A Temporal Bureau head. One of the 7 men in charge of all time. He looked down at Hayden. 
 
 `` You prevented a nuclear war. That's quite the achievement. You've been an adjuster for well over 10,000 adjustments. On your file it says that you started out as a local decade adjuster and after being noted for your skill at detecting smaller and smaller changes, you slowly moved up to a full temporal adjuster for the Bureau heads. In such a case as yours, I felt it was necessary that I come down here myself to speak with you. As a head, I can authorize many changes. And so I made a small adjustment myself. You see the list was just produced which explains what temporal changes added up resulting in the destruction of the human race. And it turns out that all of them had two things in common. First, they were all executed by you. and Second they were all approved by me. Naturally I would also be called in to question. So a small change regarding your authority to make the nuclear war change was needed. I have set a meeting among the Heads set for the exact date of the nuclear war, the very one you prevented. Naturally I ca n't have you preventing it anymore. So your swift execution has been ordered. The ripple will reach you any minute now. And with that the nuclear holocaust leaving me as sole head of the Bureau. You can feel it now, the window breaking in the apartment of your mother and father, preventing them from doing anything that morning. You have served us well Adjuster Hayden.'' 
 
 The head stepped out of the cell and into his elevator. as he pressed up and exited time. He could feel time try to grab at his knowledge of the man that no longer existed, and it failed as it could not reach him outside time. He stepped out in the year 1,000,000 toward his new office. He smiled reading the title printed on his door. `` Temporal Bureau chief''
