'Change that one thing' there ... If that was the case I would've thought the same ... Anyway, we all know that we can't change the past ...

Even Superman stop taking chances on doing so knowing that changing something from the past can just erase our present and change our future forever and mostly to something bad.

Guess we should open a thread like, "What if" and bring things from the past that changed the whole world today ... not a good idea for me, all the things that I got in my head are politics related matters ...

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Gautama Buddha)
