We have employed far less espionage than MoM did, until the FARMA war. Even afterwards, W2V spying did not go to the same levels as pre-FARMA MoM. We've had snippets of info from [T], from irregular sources, without sits, given to us. We are good at making it seem like [T] was leaky as a sieve, but that was not the case.
Furthermore, in a straight fight at the time, I think we would have beaten MoM due to sheer inactivity.
Lastly, our attitudes to others have been no different than MoM's prior to the fall, [T] prior to their fall, or tribes like Haul, CODE, Old, sheep... Compared to other worlds, same story.
To continue your analogy: Germany would have taken Poland and France even with proper warning, without a doubt. The stigma here tends to be more anti-Nazi Germany than anti-Blitzkrieg.
