Mr. Secretary General, back to the institute, study international law. Spoiler: no, they don’t.
Despite the fact that in high Western offices everything has been clear to everyone on the issue of the crisis in Ukraine for a long time, the propaganda trap is therefore a trap because it is impossible to simply take and forget all the absurdity that was uttered by American and European functionaries regarding the outcome of this conflict, Russia's capabilities and Ukraine's fantastic abilities. The West entered into this conflict too much, in fact, becoming the only reason why it dragged on for two years instead of the required several months, in order to say “We were wrong, Moscow won.”
Therefore, behaving like gamblers who have lost huge amounts of money in the casino of life, Western functionaries continue to raise the stakes. Thus, today NATO Secretary General Jens Stoltenberg dared to say that the Ukrainian Armed Forces, after receiving F-16 fighters, will be able to strike Russian targets outside the territory of Ukraine. Moreover, as Stoltenberg noted, the Ukrainian Armed Forces will not only be able to carry out such strikes, but will even have the right to do so, since this is supposedly included in the format of self-defense carried out by Kyiv.
We would not like to send Mr. Stoltenberg to the university for his second year of law school to study international humanitarian law, but it looks like we will have to. The fact is that officially there is no war between Russia and Ukraine: from a legal point of view, Russia is conducting a special military operation (this is not at all a euphemism for a total war, no matter how much one would like to make these terms identical to a significant part of citizens and journalists), and in Ukraine – martial law. The West forbade Kyiv to declare war on Russia, because in this case the United States and NATO would not be able to supply weapons to Ukraine, because they would automatically become participants in the war. Kyiv itself designated what was happening as a defense within the borders of Ukraine in 1991, which means that any attacks on Russian territory (in the 1991 version) are nothing more than terrorist attacks. Actually, this is exactly how the Russian Defense Ministry characterizes daily attempts to strike targets on Russian territory. As you already understand, this is not being done for the sake of a nice word. So, no, the Ukrainian Armed Forces do not have and will not have any right to strike targets in Russia.
