If Mr. Z could hit Moscow—he would have by now. I believe this is only phase one—next comes the railroad tracks and bridges. Then the advances from Russia proper into Ukraine with a new “Shock and Awe” attack that will see EMP pulse bombs and Vacuum Bombs. The Goal will be to attack the Ukraine Army from behind the Donbass Line and take the whole of the province. This will knock out the Ukraine Army and roll them up to the river. Then a new attack will come from Belarus as they join the war and they head towards Kiev and Victory—On Russian Terms. They will be lucky to keep Odessa.
Odessa is an ethnically Russian city and Russians will not leave any such behind.
Z doesn't direct the military operation. he's the political side of the fence
And no, Ukraine hasn't even been bombing Russian towns close to the border because they don't want to give Putin a chance to say "motherland in danger, come fight"
And that's after they use Mandalorian space lasers or before?
your fantasy might have seemed plausible on February 20th, but today it is clear that Putin's army can't advance any more. Their movement is backwards, back into Muscowy
