Never once I said it's the _only_ reason this happened (obviously). But between "it's the only reason" and "it has nothing to do with it" there's a lot of ground to cover, don't ya think?

I don't think it's far fetched to assert that the US and Germany in the 20s were extremely connected, financially speaking. How much this impacted the subsequent events can be debated.

But believing in no impact at all is just intellectually dishonest. It's a plain fact that '29 and investment dry-up in Europe caused incredible hardship on Germans (and their voting preferences in the '33 elections).
