I see what you mean but that's sort of what I meant by doing it linearly at a topic level. Absolutely, you don't want to start with the end of World War 2 and then move backwards to its causes. But I think it's entirely feasible to learn about the Cold War, then study WW2, then study WW1, etc... I don't know, I don't have especially strong feelings about it, but it definitely seems at least viable.
