If it worked the way you think WW II would have been over a good 6 months before it was. Also Japan would have never start a war as many of their best military minds knew that they couldn’t win we it started. Seems to me they had plenty of people that were willing to die, if they hadn’t we wouldn’t have lost so many boys taking Islands. You do remember that less than 10% of Japanese soldiers surrended. Also it wouldn’t have taken two bombs to end it. You do know that Japan only surrended because of Hirohito and even then the surrender only happen because a handful of Japanese Officers stop a coup and the arrest of the Hirohito?
I am quite aware of how WW2 went.
Times have changed and the Persians are quite aware of what Thermonuclear weapons are capable of.
Nothing has to work the way “I think”. Nobody can tell what will happen if the balloon goes up, but most people with any but of intelligence understands that mankind is quite capable of rendering this planet lifeless. Believe it or not, even the Mad Mullahs understand this.
