lol,
No, of course not, not remotely. Look up Kwantung army, for example, and look up what fraction of Japanese military it constituted.
That said, the religious assessment that "It absolutely was, it was a tough decision, but anyone who disagrees, is simultaneously misinformed, AND a pussy" has been a centerpiece of US's internal propaganda for many years. So you are unlikely to find a credible US historian that says otherwise, BUT - look up foreign views on the subject. Such as... those of Japanese historians. It's often a very good place to start on WW2 history - look up another country's historians' views on the topic. That's what it took for me to recognize that USSR, despite being by far the most significant contributor to the war effort, was far from the sole winner of WW2 (which was a view that was thrown at me for many years back in middle school).
That's if you are actually interested in the history and complexity of the subject. If you are just looking for LOGIC related to the subject (i.e., talking) - well, only keep in mind that logic that pushes off of incomplete information is as useless as a die roll.
