Not every statement that some Ukranians do not agree is Russian propaganda. There is WESTERN academic system studying on the history for long time, which is neither pro Russia nor pro Ukraine. If you want me to explain the history of Russia and Ukraine, their culture connection, and why Ukraine uses the trident symbol on their coat of arms, it will be very long. There are quite a lot publications on this topic, so don't worry about their views' independency. I can't imagine that they are all controlled by the Russians.
BTW, in fact, Czech and Germany has culture connection.
