The US has been using propaganda to justify its atrocities, genocides, mass murders, environmental devastations, scores of violent coups, invasions, use of chemical and nuclear weapons against civilians, torture, enslavement, human trafficking, war profiteering, and massive body count for over a century. Far worse, for far longer, and far more deadly than anything Russia or the USSR has ever done.
You’re right that propaganda is inherently neutral. When Euro-centric news outlets complain about Russian propaganda, it’s completely and utterly without standing, as most of them are part of the US propaganda machine in big or small ways. These complaints are worthy of nothing but ridicule.
