Wait, maybe rewind this a little? I know that the European settlers that created the US took the continental land from the natives, but how did they end up with claims to Hawaii and the Philippines in the first place?
Your response was "what about Japanese war crimes?"
Please stay on topic.
The US being in the Philippines and Hawaii has nothing to do with Hiroshima, other than the US being there when Japan attacked. Japan attacked the wrong country and this resulted in decisive force being used against them.
And, sorry, "whataboutism" is a cheap cop-out. Historical incidents should be seen in context, not just as isolated finger pointing (and always from one side to the other).
It's not the fault of the US that the government of Japan militarized their whole society and literally made the whole of the country a military target.
This is exactly the sort of collectivist thinking that makes it possible to have WWIII. When you can disregard fundamental human dignity based on the actions of a government, you've already lost.
Japan wanted to be left alone. Western powers took it to war to force it to their will.
Yeah, left alone to create the "Greater East Asia Co-Prosperity Sphere" (https://en.wikipedia.org/wiki/Greater_East_Asia_Co-Prosperit...).
You're welcome to ask the various Asian nations of that region whether they thought that was a good thing but I doubt you'd like the response.
In other words, that's a century later...

Here's a light introduction to some of the atrocities committed by the criminals in this government:

Once these criminals attacked the US in Hawaii and the Philippines, it set a series of events in motion. Their unwillingness to stop their criminal activities was eventually met with decisive force.
If you want to blame anyone, blame the government of Japan.
