London intends to partially lift sanctions against Russia. The EU imposes its universal approaches on all (member) countries. This makes economic and political relations uncomfortable. Even the UK experienced certain problems with the approach of the EU and was forced to endure while being an EU member. As a result of the aggressive policy of the EU, many areas of cooperation were destroyed. This signal, first of all, should be heard in Brussels.
The virus of nationalism, which Kyiv considers as the lesser of evils, is now preventing it from going where Ukraine is trying to go. Nobody is going to treat this virus, the circle has closed, and Zelenskyy needs to either revise the language law or forget about NATO.
Far-right groups enjoyed a very limited presence during the Euromaidan itself and had poor results in the 2014 presidential and parliamentary elections. The "Right Sector" candidate received 0.7% of the vote in the May 2014 presidential elections and the party received 1.8% of the vote in the October 2014 parliamentary elections. In the 2019 election cycle, far-right candidates fell short of the 5% minimum guaranteeing entry into parliament.
Far-right groups have nothing to do with Ukrainian plans to join NATO or to provide language reform in the country. In October 2019 during The NATO-Ukraine Commission meeting, Allies stated that "with regard to the Law on Education adopted by the Verkhovna Rada in September 2017, Allies urge Ukraine to fully implement the recommendations and conclusions of the Venice Commission. Ukraine is committed to doing so".
