Russia could have killed them all in 5 seconds with a tactical nuke. But that would generate bad PR.
I think the bigger issue is, Putin and some of his most sensible tacticians know that’s a last resort but his media machine is so gung-ho for a nuke launch that it’s turned into a juggernaut.
We know it’s over the top propaganda but the proles in the regions have no alternative sources of information so as far as they’re aware NATO has all but committed to a full scale invasion of Russia with a Nazi army to rival Hitler’s, backed by the Jews and the Globalists, and Russia is boxed in... so that’s brewing a sense of WHY HAVEN’T WE NUKED SOMEONE ALREADY.
