One could argue that they were in a way complicit, but not responsible. Is it Germany's fault that the representatives of a country made it seem that they were able to make good on their debts?
Representatives of a country aren't exactly magicians that can hide the anemic growth and money pissing (particularly in Public-Private "partnerships") that countries like mine - Portugal - had.
They were either fully aware or extremely incompetent, and the latter isn't plausible.
