We should write a letter of appeal to the Vienna City government:

"A Sobieski Platz is needed here, and here's why. *insert an accurate, yet simple, account of history.*"

Or perhaps Slavs just don't like propaganda. I mean, the USSR was the only Slav run state that used massive propaganda, but it was run on non-Slavic principles… Marxism. Germans and Anglos boast at any chance they get about anything, while Slavs just keep a cool head and remain humble. This has worked both for us and against us! But I do feel we can state our case about a few things just a bit more firmly :)
