Imagine that you were alive in 2500 and there had been... Say, a Nuclear bomb dropped on half the world around 20 or 30 years before hand, and you'd survived. But this bomb had been dropped by accident. Now imgaine that they had the technology for one person to travel back in time and stop this from happening, and you were that one person they chose. How would you go about trying to explain to everyone what was going to happen, and how would you go about trying to stop it (just pretend that the mistake was made by one person who got the wrong message and pressed the wrong button).
No...actually I would take the responsibility and I'd go back in time and shout to that guy 'hey - look at my schlong!' at the last second then I'd cunningly tape his fingers to his nose and transport him off into the future then I'd come back and make a global announcement.'Hey - did you know that there is a really good reason that we should have a party.' Then they'd probably lock me up for being insane and then some other random guy would accidentally blow up the entire world.
maybe, but a nuke (many nukes considering the MAD policy) would destroy everything in its blast radius, not just people.. besides.. although our collective habits don't do the world any favours, I'd say that most individuals aren't 'bad' or not worth saving.. although I guess I can hazzard a "some are very naive". Back to the topic.. no matter what you 'change' in the past, the nuke would still be fired because when *insert thing here* happened, you would have already been there trying to stop it. Whatever you do in the past will inevitably not change what you're trying to stop... hmm, don't get me started on the problems with timetravel lol.. ahh well that's the thread nuked someone should have stopped me!
Go back in the past even further than that, steal a better nuclear bomb, and blow up the people who originally blew up the rest of the world. Most likely America.
