Yeah, there is a lot of conflict potential here. Especially since the area around Löcknitz is one of two federal states in Germany where the NPD party has representation in the regional parliament. It is a fairly small representation, but still, the NPD is active there and they always seek to cultivate anti-Polish sentiment. For Poles to counter that with German bashing would be stupid and just light the powder keg that the NPD hopes to then exploit.
As cheesy as it may sound, wouldn't just a good neighbor policy be the best solution? This would allow for the rediscovering of Slavic history in those areas without being outright invasive. Though, forecasting here can only accomplish so much. We must remain in tune with the situation and play it by ear.
