It's good that you wrote word ''some''. According to description of video, it was made by AfD - far-right opposition party. If it would resemble majority opinion, probably they would have much more seat in Bundestage than they have now.
I'm trying to find any military reason for these drone attacks on the business center, but unfortunately I can't. And a repeated strike on the same building in Moscow City refutes the version of the Russian Defense Ministry that the first drone was suppressed by electronic warfare, these were targeted Ukrainian attacks on a skyscraper in Moscow, in which there are no military facilities. Simply put, this is pure terrorist attack.
I understand why Ukraine resorts to terrorist tactics - because its counter-offensive is failing. I understand, but I don't condone it. It is impossible to defend democratic values by terrorist methods. Soon even its most zealous supporters in the West will turn their backs on Ukraine, because support for Ukraine already smells very shitty.
I have no idea why this building was attacked. There is Ministry of Industry and Trade or Ministry of Digital Development, Communications and Mass Media is located in MIBC, but it doesn't sounds like targets. There isn't even guarantee that these drones were released from territory of Ukraine, after all distance to Moscow isn't such small.
Anyway, it's fun to see Russians complaining about terrorist attacks, when their country is doing it almost on daily basis and on much higher scale. And BTW, didn't you said something similar about West turning their backs on Ukraine if they won't show significant results of counteroffensive before NATO summit?
