You have no idea about the darkness and effectiveness of modern tyranny. Russia is pretty much North Korea in democracy at this point or they will become so very soon.

Putin wants the sanctions to be over. His next move will be to create devastation in Ukraine and hold civilians as hostages for the lifting of the sanctions.

In anycase, Russia will controll South of Ukraine, link up with Transnistria and even if they don't take Kyiev and don't force Kyiev into peace negociations, the will secure such a strong position that absolute control won't matter
