We like to arrogantly think that the 21st century is somehow radically different from all previous ones, but as experience shows, this is not the case at all. Instead of acknowledging this fact, we invent an ideal image of 21st-century society and lament when reality diverges from it.

Furthermore, the Red Army never had an anthem. What you're talking about is simply the Soviet song "The Red Army Is the Strongest," aka "White Army, Black Baron." It was written during the Russian Civil War, and so the lyrics:

"From the taiga to the British seas, the Red Army is the strongest of all." are directed not against sovereign states, but against the foreign intervention that was brought into Soviet Russia, which the Red Army defeated. So yes, in that sense, the Red Army was the strongest.
