Lets play a mental exercise game. Hypothetically, what if the Russians are not going in like bulls in a china shop and wrecking havoc all over the place, but are going in and trying to maintain civil services (water, electricity, gas, hospitals, etc)? What if they are moving in methodically and doing their best to not break any eggs because they have no interest in destroying or rebuilding Ukraine? They could easily pull a shock and awe like attack and level the entire place and create a humanitarian catastrophe, but that isn't necessarily happening right now.
There are already 1 million plus refugees. You are absurd.
