I think this is more like incompatibility between the "central-continental European cultural area" (+ some "balkanic-European c.e." elements for Hungary) and "west-atlantic-postcolonialist-European c.e." and this is very mild and will go away when current politicians trade seats. Hungarian, Polish, Bulgarian, Romanian etc. people can cooperate well amongst themselves and with eg. Germans or Austrians, if nobody is deliberately stirring hate.
Maybe Poland and Hungary could serve as bridge to Russia to solve the worst incompatibility, that between the mindsets of west-atlantic-postcolonialist-europeans and mindsets of russian-europeans. But I would not have much hopes, these two groups are very incompatible... each would probably find it easier to get along with the Chinese or the Americans that with the other. And there's also eastern European countries like eg. Romania that have better closeness / similarity / affinity to west-atlantic-Europe and the US than to the central-European ones and would rather burn themselves than serve as a bridge to Russia... Europe is complicated...
German (continental) European de-facto-leadership + eastern Europe to be the bridge could work in theory though...
