It is clear many did not read the articles presented in OP.
1. Harry Truman was a racist who openly stated he hated Japanese people as early the 1920's . I would wager that this mentality played a factor in his decision to nuke. Can you imagine if Trump did something similar against a group he's racist towards?
2. Pearl Harbor is a joke of a "eye-for-an-eye" argument. 2500 military personnel are not innocent lives. The Japanese only targeted military targets, not civilian populations.
3. Two wrongs don't make a right. Japan may have committed heinous crimes of its own, but none compare to the level of dropping an experimental death weapon without understanding the repercussions for the future.
On the topic of of Nanjing, just like the so called Armenian genocide, actions committed are highly circumstantial and not clear cut. Death figures from this era are never accurate and can be twisted as needed for political purposes.
In case you are curious, the Allies during WW2 committed more than their fair share of war crimes (https://en.wikipedia.org/wiki/Allied_war_crimes_during_World_War_II)
Of course you rarely hear about them as the winners write history. There's no one left to hold the US accountable.
4. Nukes were completely unnecessary as Japan was, by the end of the war, essentially and island nation cut-off from the rest of the world. The Soviets were rapidly invading Manchuria with plans for invading the Japanese mainland. The US had the naval advantage with a blockade pretty much cutting off Japan's life-line to food/energy imports.
They would be forced to surrender or have their people starve, which is a comparable effect to mass murder of innocents via nuke.
5. The US was playing realpolitik by initiating the cold war with an arms demonstration against Russia rather than genuinely expressing interest in not prolonging the war.
