The Russian Federation attacked Ukraine again. They bombarded a sovereign country. The country, which ratified the Ukraine-EU Association Agreement and became the candidate for the EU accession. However, the Russian Federation did not hesitate to assault Ukraine. They blatantly aim to punish Ukrainians for their European choice. 
Thus, the Russian aggression against Ukraine calls all European countries for action. Among diverse measures that are already being taken, there is one more way to resist the war. EU countries could and even should reconsider their policies and regulations, regarding the granting of EU citizenship to Russian Federation citizens. Keeping the existing legal status quo, which allows Russian citizens to continue using the benefits of dual citizenship, presents the imminent threat to European Union wellbeing. 
Being a country’s citizen means that one has certain rights and obligations to the country and that the country, in its turn, has certain rights and obligations to its citizens. The constitution and military doctrine of Russian Federation, according to the Part 1 (the article 59) and Part 2 (the article 15), require all Russian citizens to abide the law unhesitatingly, which among other things, obligates all citizens to defend Russian Federation. This duty is imposed on all Russian citizens, regardless of their actual place of living or dual citizenship. 
According to the Russian Federation, the war, which it started in Ukraine, is the defense war. This Russian “defense” military doctrine represents a complex of actions, which include the following elements: 
●      The actions targeting the murder of civilian population
●      The actions aiming to the destruction of civilian infrastructure and households.
It’s important to note, that it’s not for the first time that the Russian Federation started a war, driven by the desire to defend the rights of its citizens outside of Russia. They keep using Russian citizens living abroad as an excuse to push their aggressive geopolitical agenda. They bring their ‘defense” even to those who never asked “to be defended”.
