The analysis of cases gathered in Polish online media in the framework of the project "Information warfare in the Internet. Exposing and countering pro-Kremlin disinformation in the Central and Eastern European Countries" demonstrates that pro-Kremlin propaganda is extensive and multi-channelled. The narratives and "big subjects" uncovered during the monitoring of over 50 web sites involve, among others, the following messages:, "Ukraine is falling apart", "NATO is provoking Putin", "NATO acts like Hitler", "NATO is a tool of America", "US will abandon Poland in case of a war", "Polish authorities are Russophobic ", "Poland should join fellow Slavs", "Donald Trump is a great opportunity for Europe".
