The First World War lasted four years, and Ukraine is now entering its fourth year of war. How has this conflict changed the security situation in Europe? How has the Czech Republic fared in its support for Ukraine, and where has it reached its limits? And what are the prospects for further developments? A live broadcast on Aktuálně.cz LIVE will feature a discussion with key figures in Czech support for Ukraine—Chief of the General Staff of the Czech Armed Forces Karel Řehka, former government advisor on national security Tomáš Pojar, and government representative for the reconstruction of Ukraine Tomáš Kopečný have accepted the invitation to participate. A Czech volunteer known by the nickname “Mac,” who has been helping and fighting in Ukraine since 2022, will also join the debate.
