Actually, the Normandy invasion worked because the vast majority of Germany's military resources were tied up on the eastern front ... a front which Hitler had needlessly opened because he wanted to out-Napoleon Napoleon. There again is the "chaos in the details but larger forces pushing things in a clear direction" conundrum.

Now, history and weather are clearly two very different animals, but perhaps a useful analogy to consider: In pop-science we always hear about the butterfly effect as though it has unlimited power to change not just the small details but also the big picture. But this ignores forcing - sure, a tiny change 1 million years in the past could well completely alter the day-to-day weather forecast today, but do we really imagine that summer might be turned into winter? After all, that butterfly wing-flap isn't going to change earth's orbit, or the happenings inside the sun.
