Not defending the Russians, but maybe Putin wanted to save most of the ukr. infrastructure for the future citizens of Russia....could explain the tippy toeing.
Be warned however, most of the information is bogus.
Putin is in a desperate fight and isn’t tip-toeing around, the Russians are just not very competent.
While accurate information is scarce, we can see that the Russians are struggling as the months are passing, some things like his navy problems and lack of Air Force, manpower problems, equipment issues, and supply problems, are observable even at our distance and with lack of news coverage.
