In the speeches and statements I have seen, there are a few differences. When addressing the European leaders, the Ukrainian leader speaks English without an interpreter. In addition there aren't any non-christian religious symbols in the image or speech, and when it comes to cultural symbols it is almost exclusively in terms of European union.

I have read/listen to a bit of research when it comes to diplomacy and tensions between nations, and a common theme is that its the small things that tend to have a large impact on kinship, trust and cooperation.
