The Russia-Ukraine war began on February 25, 2022, after months of tension and the presence of Russian military forces on the border of Ukraine, with the order of the Russian president's all-out military attack. Putin's justifications for the military attack on "special military operations" in Donbas and the non-occupation of Ukraine by Russia were based on humanitarian intervention due to the commission of the crime of genocide by the Ukrainian government in the east of this country. But Putin's most important justification is based on individual legitimate defense in advance due to imminent threats from Ukraine and NATO, and collective legitimate defense in support of the self-proclaimed states of the Donbas region, which Russia previously recognized as independent states. Had been recognized and a treaty of friendship, cooperation and mutual assistance was established with the leaders of Donetsk and Luhansk. Therefore, the purpose of this study is to examine the war between Russia and Ukraine from the perspective of the right to resort to force. Therefore, this research seeks to answer the question: Are Russian legal arguments for resorting to force justified from the point of view of international law? is The research method of this article is descriptive-analytical and the method of collecting information is library-reference. The findings of the research indicate that Russia violates the rules of international law and the right to territorial integrity and political independence of Ukraine, and Russia's reasons for legitimizing military aggression against Ukraine are not justified.
