Former Polish president Lech Wałęsa has written an open letter to Donald Trump. The document, signed by Bronisław Komorowski, Adam Michnik, and over 30 opposition activists from the Polish People's Republic, is simply a consequence to Friday's conversation between the US president and Volodymyr Zelensky. "We watched the study from your conversation with the president of Ukraine with horror and distaste," the signatories emphasize.
