They are not only so dumb, they also desperately trying to pass off what they wish for reality. They do not have enough resources, they are trying to increase the production of equipment, as always they multiply quantity at the expense of quality, and in the end they suffer themselves. They are ready to go to the most cruel, most stupid, destructive deeds just to please their leader, who himself does not understand where reality begins and ends. An adequate person cannot understand this supreme stupidity, because in order to understand it, one would have to abandon objective perception and immerse one's life in a myth that has been created for decades and destroys the lives of millions of people, both in their own country and in other countries.
That is true.Russia has been immersing themselves in such a bad situation that even if the war ends right now they need a good 20-40 years to go back to the state they were before starting this illegal war.They have committed horrible war crimes which thanks to the technology right now are well documented different from wars that have taken place before like WW2.Their leader is the sole responsible for this failure,he started the war as he did not want NATO near his borders and yet he has added another 1300 km borders to Russia from Finland who joined NATO a couple of months ago.I am not astonished by this though,I know what kind of evil Russian government people are but what I am astonished is that ordinary Russians support their government,that is the sad part of this.
