Humanely, war will only make everyone miserable, especially the people. but behind the war, of course, there is a separate mission from the rulers who certainly want their goals to be achieved with sacrifices that have been calculated beforehand, so that if their goals are achieved, then they will benefit, and of course they also make cooperation with other countries to supply weapons and other equipment, for example .
You are talking very vaguely about the mission of the rulers who start the war, and about their goals in a particular war.
In February last year, Russia attacked Ukraine with its eight armies, some 180,000-200,000 in total. Moreover, the attack was from three sides: from the south, from the side of the previously captured Crimean peninsula, from the east, where Russia had attacked the Donetsk and Lugansk regions of Ukraine eight years before, and also from the north, from Belarus. What then, in your opinion, was the mission of the rulers of Russia, making such an attack, and what were the goals in this war?
