You couldn't predict WWII in 1920 because one major factor hadn't really appeared on the scene yet -- Adolf Hitler.
I think the Civil War and the _attempt_ at an American Revolution could have been predicted. The presence of troops to crush such a revolt is pretty good evidence that it WAS predicted. The idea that it would succeed is another matter.
wolf: I don't think fulminate of mercury (and thus percussion caps and primers) are out of reach for a backyard chemist. Even smokeles powder isn't (nitric and sulfuric acids were known to the ancients, I believe -- certainly in medieval times. And the sulfuric isn't strictly necessary), though of course black powder is easier and safer to make.
