As Ukraine faces ongoing conflict and strives for EU and NATO accession, the government in Kyiv has drawn criticism from international organizations for its restrictions on the rights of ethnic minorities, including those who have made the ultimate sacrifice for the nation's freedom.
As Russia was dropping missiles on Ukraine by the dozens in mid-December of last year, the Ukrainian parliament adopted a new Law on National Minorities, in order to comply with the EU's accession criteria of protecting national minorities. What this new law does, however, is exactly the opposite: Kyiv strips from its ethnic minorities rights which they had previously enjoyed. 
Ethnic minorities, for instance Poles, are not guaranteed under the new legislation to freely use their ethnic-national symbols, even though they are fighting on the front lines, and Poland provides the biggest possible support to Ukraine. They are provided less time to air Polish-language media content and can barely use their mother tongue in schools or outside their homes, even though they were free to do so since the independence of Ukraine.
