Point is you have no clear idea what could/would happen.

We have always had genocide, so that is not Hitlers fault.
Your plague statement is just wrong.
Israel and well everyone has been on verge of war - though would Israel be there if no Hitler?
Wars all over the East have been going on long before Hitler.
Economy is not directly related, unless perhaps WWII went wrong and then it may have never rebounded as it did - nor would we have the technology that gave us our economy today in the first place.
Environmental disaster - again not related unless your adding in the very few atomic meltdowns and uses in war. Though on the flip side atomic energy would be one of our safest forms of energy if we actually used it more, and that too would effect not only the economy but assorted crap in the Middle east.
