the objective measurement is: 1: russia shares a land border, logistics are trivial and easy. 2: ukrainian geography is perfect for russian military doctrine. 3: air superiority, the number of planes russia has vs the amount of aa units ukraine had (2022) was insane. russia should have been able to saturate the skies and destabilize the ukrainian government, but didn't. 4: money, equipment, manpower. russia has all of this in abundance. but instead of using it all in a focused strike to take control of ukraine before western aid can arrive, they wait.
