Rostislav Ishchenko – who also has pushed the idea that Russia should occupy the Baltic states – this week had a chance to present his current views on Ukraine on Russian TV, finding Russian ground forces would suffer significantly if they decided to go for Ukrainian cities. Other participants of the “Evening with (propagandist) Vladimir Solovyev” proposed to take Aleppo as an example (see here, or here in English).
There are a few points such “discussions” do not consider (and suggest the public might be lured into an adventure against Ukraine). Those points are for example that Russia will not fight “terrorists”, but a regular army and possible effective weapons against Russian aircraft – such as the infamous Buk-missiles – or the fact that Ukrainians have defended attacked targets stubbornly (e.g. the Donetsk airport).
