If you could change history what event would you change...and why?

I have only two things that I would never do again. 1. Give a family member "Power of Attorney" during a medical crisis. 2. Co-sign on any loans.

I would stop the assasaination of Abraham Lincoln because he would have made things even better for the slaves if he had been allowed to live. He was cut down in his prime because he was anti-slavery.

At one time I thought surely I would go back and save the Kennedys, but knowing what I know now, I would go back to the night Mama Bush was conceived and put salt peter in Mr. Crowley's drink. That would have put the kabosh on a whole lot of monkey business, including the Kennedy assassinations.

I personally would not change anything in the history because I believe that everything (even the most horrific things) happen for a reason and have god and bad consequences (for example nobody likes war because they are bad, no good in them? but world war made a difference, it helped woman to emancipate because they were forced to do things that men did not allow them to do before... god and bad things in everything). About consequences of changing the history... my point of view is like this changing the history does not change the presence, because if you go back to the history and change it the present is already a consequence of that action. a mystic circle. another thingy (example maybe)... is it possible to go back in future to kill your parents before you were born? my guess would be that this is impossible... because if you would kill your parents you would not exist and if you do not exist you can not go back in the past to kill your parents.

I just hope I was born 6000 years ago!

if i could change i will change the war system and border system every person can go anywhere easily without passport and visa every where would be peace

This is a good topic my friend, one of my pet peeves!;) If I'm to be asked, I wish that our economy was still as the same as what other superpower countries are now enjoying. Back then, Philippine monetary exchange was as the same as the US. As I was told, my grandparents and even my parents used to spend small amount for their daily means. They don't have to worry much on what they'd eat, because the supplies then was abundant and clean. Life was just simple, people are contented and there was no pollution. I wish I have lived during these times, not too many complications for me to worry for a day!;)

Life is nothing short of a long serie of mistakes. So there is no doubt that I would change everything in history... and I would also change my personal life. But we could only change those things today because we have learned from those mistakes. If we went back in the past without that knowledge... we would probably make the same mistakes again. World War 2 could have been prevented if we had knew that Hitler was lying to us. The climate change could have been prevented if we had knew in the 1950's what we know today. If we had not left Saddam Hussein in power in 1991... we would not be in Iraq today. If Europe had not surrendered its colonies to the do-gooders of this world... we would not have to deal with multi-culturalism, racism and illegal immigrants. And perhaps... there would not be such things as third world countries today... because the west would have developed those countries. A small country like France spend billions every year to provide aid to its ex-colonies in order to prevent those people from emigrating to France. If France had retained its colonies... it would have been able to develop those colonies and make them sustain themselve. France would be richer for it... and so would be the colonies. Australia is a colony... and look at us! Sure... the Aborigines lost their land... but they were not exactly doing something with it. Furthermore... we feed them by handing them a cheque every fortnight. We gave them some of their land back... and now they charge us a toll to walk on it.

Whilst it would be tempting to change things I don't think I would interfere with history. Aside from the Butterfly Effect I feel people would become entirely reckless because you would no longer have to take the consequences for your actions - just go back and fix it. Also we would become so pre-occupied with alternatives that we would never realy get anywhere. How many times have we thought if only I had done that instead? If we could go back and change history to see what would happen if we didn't like it we would change it back to the way it was and so on and so forth. Personally I think that hindsight is as much a gift as a curse. Whilst it is a nice idea to change the past with the knowledge we have in the present surely the point is that we learn lessons from mistakes and change the future - something that we all have the power to change.

Ok as much as I would want to change something I would not. By changing stuff in the past, some things might change in the future. And my life would have probably turned out different. So the best is to leave things like they are I think.
