Americans did invade part of the Japanese home islands such as Iwo Jima and Okinawa. The battles were atrociously brutal and horrendous and 94 % of Japanese forces were killed and Americans suffered enormous casualties. Because the resistance had been so fierce and ruthless, and because the Japanese military had declared that 20 million conscripts were ready to take arms to defend the Empire. Many American military officers wanted to just use the nuclear bombs and be done with it.
There was also the issue of the nascent Cold War; the Soviets wanted to invade Japan and turn it into a Communist, satellite country and Americans wanted the use of the two bombs to also be a show of force to make Staling reconsider.
The social class structure in Medieval Europe would be renowned as an “feudal” social structure. After the rank of king, the hierarchy was the nobles, the knights, the clergy (religious people), the tradesmen and the peasants
I am pretty sure this is correct.
