Ukrainians often speak of the disconnect between how the media wants to portray “the Russian people” and the truth of the “common Russian.” I think the Ukrainians understand this better than we do and that “the common Russian” does see a greater Russia that should be ruling over the former bloc states of yesteryear.
The Ukrainians understand the disconnect because they lived it during the Soviet Union. Almost every Russian/Ukrainian (and other citizen) that wasn't 110% indoctrinated into the Soviet ideology knew they were being lied to. They knew the West wasn't 80% unemployment and alcoholic like they were being told - and that was before the internet and the free flow (relative free flow) of information.
But that's no excuse to make a poll driving a lie that Russians want to attack Poland (which is a lie perpetrated by Ukraine to elicit an action by the West against Russians). I know you said you're not against the Ukrainian lies if it means they hurt Russia, but this is a perfect example of how lies can push greater conflict.
