Changing the past

[OmegaRuby and AlphaSapphire]

If I could go back in time I will go and prevent World War I from happening. That way I'll also impact World War II as well. As without the first WW the situation Hitler used to take over wouldn't have happened as Germany would still be as vibrant as before, not war torn and depressed. Also by stopping WW I it could potetentially minimize or even eradicate the great depression as the first WW lead to the US becoming isolationist. Also by stopping WW I and II in the process the creation of Israel would be shifted a couple of years or never exist at all. This in turn would change the players of the Middle East...of course this may divide them even more due to the lack of a common enemy (well at the beginning)...
