This thesis was spread in the Ukrainian segment of Facebook. The reports say that Ukraine allegedly did not declare martial law or war on Russia in general, which means that Ukraine is fighting illegally. In particular, they argue that such actions of the Ukrainian leadership are involved in an irresistible desire to seize Western resources.

There is a war going on in Ukraine, and this is understandable without announcements. For example, politician and diplomat Andrii Shevchenko explained in a comment to MediaSapiens that from a legal point of view, a declaration of war is an external matter of the state. He adds that international law does not focus on words or statements, but on actions. Therefore, from the point of view of international law, what is happening is an obvious war, a violation of the sovereignty of Ukraine.

Back in March 2022, former Deputy Minister of Defense of Ukraine Hanna Maliar explained that there is no need to adopt a special law or decree on declaring war. She cited Article 3 of the 1974 UN Resolution on Aggression and emphasized that an invasion or attack by the armed forces of a state on the territory of another country, bombing or blockade of ports qualifies as an act of aggression.
