A day will come when no propaganda will be useful, everything will change then. In the end of the day there is not much doubt that the US, FOR ITS OWN CITIZENS is far more democratic than Russia and has a lower crime rate, corruption and alcoholism though, no propaganda can change this.
The problem is that also the west has its share of wrongdoings and the world will actually improve only when we start to give everyone's life - honestly - the same exact value.
