It's barely been 3 days. It's incredible how everyone (including leaders, allegedly even "operative" leaders like Putin with a paramilitary background) now expects wars to last a few hours. Even swift one-sided conflicts like Desert Storm and Desert Fox lasted a month or more! To expect less than a week from invasion to regime change in the capital is just stupid, if the Russian generals really worked on that basis they are not fit for command.
I read a story today that Russian soldiers were sending Ukrainian women photos on Tinder. The story alleged that they expected to be treated in a friendly way upon arrival. This may reflect the general sentiment in the Russian chain of command.
