To be clear, I think it would be a bad move ethically and strategically to bomb Russian cities.

I just think sometimes in certain conflicts against certain opponents, this can yield the horrific results so desired by the people giving those orders.

It CAN increase resolve. I think it probably would for Russian civilians. But strategic bombing of cities can also completely break opposition. Russia succeeded this way against Syria with completely annihilating their cities. Those same commanders that got their experience in Syria are running the show now in Ukraine.
