If you do not wish to engage in an argument, then don’t. Do not instead post little mocking snippets: it’s not just rude, it’s counterproductive.
Perhaps your point was not that dropping the bomb was not necessary in the summer of ’45 — as it patently was — but that were it not for US conduct prior to 1941, the US involvement in the Pacific War, which culminated in the atomic attacks, would never have been necessary.
The US would likely never have been attacked in the first place has we not resisted Japanese hegemonistic demands in the first place. The US was not inherently Japan’s enemy, but Japan needed oil and rubber to continue its dismemberment of China, and the US and Britain refused to supply them.
But the then-recent experience was that allowed aggressive opponents to expand their territories merely delayed war, at the cost of allowing the aggressor to seize the initiative. Again and again, Britain and France had allowed Axis forces to invade third countries in Europe and North Africa, hoping to appease them, until France itself was invaded and subdued and Britain was put under siege.
Maybe the strategy that had failed so awfully in the West would have succeeded in the East. Maybe once Japan had established its Greater Asia Co-Prosperity Sphere, it would have been satisfied and left Australia, the Pacific Islands, and the US in peace. This is your best-case scenario: some half-million Japanese civilians would have been spared, at the bargain cost of only 5 or 10 million dead in China and Southeast Asia.
This is only my opinion, of course, and distinguished from your opinion solely by having some facts and analysis to back it up.
