One of the older polish internet memes is “Russia is not a state, it’s a state of mind” based on weird Russian social media. But looking at Poland, it’s at best pot calling kettle black (and adding history to that it’s more of a black hole calling kettle black) so Poland is a state of mind ever more. Plus i created that account to shower some polish facts on unsuspecting chapo people so Poland needed to be in username.

I don’t really think that Roman victory back then would do anything to prevent the rise of Germany as a nation, Rome was simply unable to permanently conquer Germania as the subsequent decades clearly shows. And even if they did managed it, it would probably actually speed things up - note how Germany for the most of their history were disunited.
