Lol could take years correcting some of the people here. Island to island combat would have cost 500k more lives on each side minimum. So basically, 100k died so 1 million could live.
Not to mention we gave Japan a warning before dropping the bomb, they chose to ignore the warning each time and paid the consequences. Essentially, they made the decision not us. We threatened to drop a 3rd bomb (which we didn't even have built at the time) and ultimately they surrendered. People should do a little research before arguing a silly point lol
