"Ukraine has been building its capacity to use humour as a strategic communications tool since Russian first invasion in 2014. After Russia launched the full-scale war in February 2022, this often grassroots effort was multiplied by many new actors joining it. Foreign supporters of Ukraine stepped in to expose lies of Russian officials in social media, resulting in a creation of NAFO movement. The use of humour by the Ukrainian government officials also pushed the boundaries of what is considered acceptable in digital diplomacy. Numerous jokes and memes have been created that will remain in the historical record of this war, such as the “Russian warship” meme, “sunflower seeds in a pocket”, “bavovna”( cotton), and others. However, humour should not overshadow the terrible reality of war Ukrainians have to face daily until this day. It should not distract attention from the need for Ukraine to win and Russia to be held accountable for its war crimes. Humour helped Ukrainians cope with the trauma of war and preserve mental health. For foreign audiences, especially in the West, it helped to introduce Ukraine as a country that is a part of the same cultural space, has similar values, and is worthy of support. Witty jokes and creative memes opened a window for many to discover Ukrainian history and culture. Satire helped to expose the absurdity of Russian imperialist ideology and propaganda narratives the Kremlin used to launch its invasion of Ukraine." (Conclusion)
