Dunno which clowns downvoted you. All attacking civilians does is make them resolve to destroy whoever attacked them. History has proven that time and time again, but some people are too dense to understand the concept. Military and war production are always valid targets, civilians are not.

The war really can't have more support than it current does in Russia. Pretty much the whole country is actively or passively supporting it. So this theory has already been soundly debunked. The Russian people care only about their own situation, and until they feel the results of this war, there will be no real opposition. Support can't go up from here, but with some help it can go down.
