Trial by War - Did Stalin withstand it?

War is a bloody exam not only for the army, but also for the state, which during the fighting proves its viability and the right to exist. The Soviet Union, the test of the Great Patriotic Warred with honor. But did his command of the Red Army and Personally Stalin?
Why a pre-war slogan: & quot, beat the enemy with low blood, in someone else"s territory & quot, was turned inside out - exactly the opposite? Who to ask for & QUOT, Shapcoozing & Quot, and the underestimation of the enemy? By whose fault, the Red Army washed four years with blood, often & quot, bold enemy corpses & quot,? Why the necessary & quot, work on errors & quot, was completed with such a delay, command so many times - came on the same rake & quot, and the Great Victory became & quot, a holiday with tears in my eyes & quot,? And the main question: was it possible to win a war with smaller losses smaller than blood?
