The Use of Force by the Russian Federation in Ukraine

The Russian-Ukrainian War has significantly impacted the international community, making it crucial to examine the war responsibility of all parties involved under international law. Through this paper, we aim to prove the illegality of Russia's argument and exercise the right of pre-emptive self-defense. To achieve this, we propose a new set of elements that can be used to judge pre-emptive self-defense more clearly. In light of the illegality of Russia's actions and the ICC's background, we further seek to determine both Russia's national responsibility and the individual responsibility of the war initiators. Our paper also offers a potentially effective arrest plan that involves coordination with specific international organizations and subjects. However, given the ongoing dispute around humanitarian intervention by the United States, humanitarian intervention must play a crucial role in the Russo-Ukraine war. The paper demonstrates the legal basis and necessity of humanitarian intervention in the current situation.
