This whole operation is taking place under the sign of an acute shortage of personnel on the part of Russia. Putin refused to call for mobilization (and still refuses) and also refused to carry out mass bombing to minimize civilian casualties. Both of these decisions separately are correct, but taken together at the same time, in my opinion, are a mistake. Let's see how events will develop, Russia does not plan to abandon the originally declared goals of the operation.
You, as always, distort the objective reality that is taking place in Russia's war in Ukraine. Putin would have announced a general mobilization in Russia long ago if he did not see the danger to his rule from such actions. To announce official mobilization in the country is actually to admit that the Russian regular army is suffering heavy losses in Ukraine and is not coping with the assigned occupation tasks. And this also means that Putin himself did not fully plan his "special military operation" and made a big mistake, and the people will not forgive him for this. In addition, Putin understands that the general mobilization will cause serious discontent among the people. It's one thing to sit on the couch in front of the TV and agree with television propagandists about the attack on Ukraine, and it's another thing to participate in the war, where they can get killed. In addition, the mobilized need to be clothed, fed, issued with weapons and provided with equipment, and Russia already has problems with all this. Therefore, mobilization in Russia is carried out, however, covertly and partially. But after the military failures in Ukraine, fewer citizens want to be cannon fodder in Ukraine. Therefore, Putin has to recruit mercenaries in Syria, Belarus, the countries of Central Asia and even prisoners in their prisons.
As for the shelling and bombing of the territory of Ukraine by the Russians, this is happening in full. On the territory of Ukraine, Russia has already fired more than 3,800 missiles, and fires at the civilian population every day and with all types of weapons. Where the Russians pass, 80-90 percent of Ukrainian settlements turn into ruins. Therefore, there is no need to tell fairy tales that the Russians are worried about the peaceful citizens of Ukraine.
