That's what Putin and his flunkies would like to believe. Spetsnaz will be planning for a very different scenario, that being an ongoing war of attrition and insurgency.
Also, the Ukrainian side has the strong support of the people, many of whom have taken up arms.
While I'm sure that Spetsnaz can easily kill AK toting grannies and teens it ain't a good look and the rear end of the Russian invasion will also suffer ongoing heavy losses.
