Japan reaped what they sowed.
And btw we bombed many Japanese cities with conventional bombs and thousands upon thousands were killed there too.
Hell we literally immolated 25,000 or more in Dresden when we firebombed the city and razed it. People died for weeks after the attack from horrendous burns and infections. But the Axis started the "total war" gambit and they lost when it was turned around on them.
This isn't Hiroshima or Nagasaki, it's Warsaw 1945.
That's why I shed no tears about Dresden.
