I'm genuinely confused whether you are capable of making a single argument that doesn't consist of "what about this other thing, therefore..."
This is not an intellectually strong or winning argument.
It is not whataboutism, it is comparing two similar cases.
Making numerical/mathematical comparisons between similar events is a fundamental aspect of human reasoning.
If you simply close your eyes and ignore analyses of civilian casualties in other wars in order to get some sense of what can be realistically achievable, then all you are accomplishing is blinding yourself and reveling in ignorance rather than seeking truth from facts.
It's completely whataboutism lol. It ignores the definition of the term and facts behind it for an incredibly simplistic "gotcha" statement.
No different than when Computer89 pulls the "how could ____ be racist when Trump said the same thing?" card.
And, respectfully, if you're saying no war crimes happened because this is similar to how America conducted its war in Iraq/Afghanistan, then, buddy.... it's not gonna work out for you.
