I think strategically it's also something of a courageous plan - missile attacks on hospitals, blocks of flats etc, energy infrastructure etc.. is far more likely to ensure that ever larger quantities of ever more capable weapons systems make their way to Ukraine.
Vlad has probably made the calculation that the atrocities, and the poor living conditions brought about by the damage/destruction of Ukraines power generation and distribution system - as well as his long standing belief that western Europe will cave - give him a negotiated result before the Ukrainian army defeats the Russian army.
He might be right, but he might not...
