It is almost the literal definition of shock and awe. It may be miscalculated (and it is), but its "here's what we're prepared to do"- be afraid. As is the massive convoy, as is- arguably- Putin's entire Ukrainian invasion, war crimes and all.
A faltering superpower trying to prove its relevancy.
Pretty sure that reactors belonging to Syria, Iraq, and Iran have been attacked by foreign powers, although Iran's was attacked via cyber, and neither the Iraqi nor Syrian facilities were running when they were bombed.
That’s beyond shock and awe though. First time ever that a nuclear facility has been attacked by a foreign regime. The largest one in Europe at that.
