Russia was publicly furious about the shelling. The western reaction was either a perplexing "Russia shelled themselves" or "they asked for it by having their military there / shelling across the river from that location".
IAEA, as a supposedly independent agency, was invited in to have a look and they said nothing about the shelling of the plant at all in their report. Again, Russia was furious.
So, it's not really a surprise that theyve declared open season on nuclear power plants.
