Complete nonsense.

Based on actual casualties received on Okinawa, projections for losses of American soldiers to invade the main Japanese islands were from 300,000 to 1 million. DEAD.

Casualties for Japanese civilians and soldiers were an order of magnitude higher.

The Japanese military command was preparing for a suicidal defence of the homeland - the emperor had become a puppet of the maniacs directing the war.

The A-bombs stopped the war, and saved millions of lives. A horrific sacrifice. But a good sacrifice.
