It's not about steamrolling, never was. The whole point of the exercise was to install a puppet government. In Ukraine, the TV actor installed by the Biden administration is currently the acting president. The moment funding runs out - so will he.
Being steamrolled requires Russia have the logistics to drive a steamroller more than a hundred yards. There is a reason it was intended to be a three day war.
Bombing a school is unconscionable but its a shadow of Russia's crimes in Ukraine.
Surely, Ukraine being such an awefully corrupt country, Putin was easily able to bribe his way to Kyiv and take it in three short days. Oh, wait... maybe someone is spewing russian propaganda here?
