Analyzing the situation from a legal point of view: The ongoing situation of the Russia-Ukraine War.

Russia's justifications and arguments, legally not politically, according to Public International Law with analyses to the legal notions of Self Defense & Prohibition of Use of Force under the UN Charter.

Russia invaded Ukraine on February 24. Three days before the attack and on the day of the attack, Putin gave speeches justifying the invasion. Crimea, Donetsk and Luhansk, cities in eastern Ukraine, freely made their choice to be part of Russia, and Ukraine attempted to undermine their choice by activating terrorist cells and operating a terrorist underground - with the international community's support, Putin claimed. The residents of these territories were suffering from indiscriminate killing, Putin said. Therefore, Putin saw "no choice" and recognized the independence of the regions at the end of his February 21 speech. This is proof that Russia is "under attack" by the West, he claims, and serves as immediate justification to defend itself by launching the operation. On another note, the past years showed that NATO slowly expanded its sphere of influence after adding several European countries, and its history has shown that it does not fear launching offensives into countries it deems as threatening, such as the NATO bombing of Yugoslavia and US actions in Syria, Libya and Iraq. If it would add Ukraine to its sphere of influence, advanced missiles could be positioned near the Russian border and could reach Moscow in almost no time - in some cases within minutes. This is akin to a knife being held to Russia's throat, Putin said. The principle is simple: A state cannot strengthen its own security at the expense of the security of other states. In Putin's eyes, this is exactly what Ukraine is doing.
