“Brazen” Ukrainian attacks in Russia? Ex-US general warns of “terrible recommendation”. Ukraine sees the attacks as a legitimate means of defense - after all, Russian oil is also used on the front, somewhat as fuel for tanks.
Russia should also be hit economically by the attacks - and morally: the Russian people should feel that the war in Ukraine does not stop at their lives. Officially, the US Department of Defense has now declared that it does not support Ukrainian attacks on Russian oil refineries.
