I believe if Hitler were not available, another man would become the leader of the Nazi party, and the war would still be fought. This other man could possibly be a brilliant militarist who would not make the mistakes of Hitler and put the Allies in a position of having to negotiate an armistice giving Germany many concessions. With the above scenario, the war might last longer causing perhaps your grandfather to be drafted, killed in action, preventing your birth. Who knows?
When it comes to one of the worst events in world history, it's not feasible to dissuade yourself with irrational fear of worse happening -- especially when it is 100% unsubstantiated fear.
Speak for yourself. Altering past events is inherently and completely unpredictable. For all we know, Hitler's Germany IS the result of some alteration of other events.
The whole premise of this thread is purely unsubstantiated speculation, so any answer is just that. I am never irrational, and no matter how bad it was, it still could have been worse.
I disagree. Having no ability to know even the range of possible outcomes substantiates an argument for not changing things.
That seems silly given we go through the same inability to know the range of possible outcomes when facing problems everyday.
I would have tapped Buzz Peterson's drunken wife when I had the opportunity that night she was visiting a friend in Johnson City back in the early '90s...
But those decisions are made in the present, so the outcomes are only in the future. This would be outcomes in the past, affecting the past, present, and future. I'm not into playing causative Jenga.
The question needing answered is whether time travel is possible? How can you go to the future when it has not happened yet? If you could return to the past, then there would be a future.
