Michał Kujawski: How did it happen that within just three and a half years from declared brotherhood, disputes and worsening moods appeared in Polish-Ukrainian relations? Łukasz Adamski: There’s no simple answer – it requires broader context. Certainly, it’s hard to expect that such intense sympathy between nations, as we saw at the war’s outset, could last long. Mutual goodwill was the result of strong emotions – Ukraine was brutally attacked, and the threat of war loomed over all of Europe.
