The measures that would work such as direct sanctions and seizing the assets of a bunch of oligarchs, Putin and his ministers? Which were step 1? Or freezing the Russian central bank's foreign currency reserves?
Furthermore, 2 weeks in, Ukraine is holding out, Russia is bleeding men and equipment, and their advance is pretty much stalled on almost all fronts. They're mobilising museum pieces from the Far East and random civilians vehicles to send to Ukraine, so it doesn't seem like the equipment situation is great. I doubt a mass mobilisation will be gladly accepted by the Russian population, so to what extent they can deal with those loses is yet to see.
Even if Russia manages to conquer all of Ukraine, they couldn't occupy it for lack of troops.
