Sure I get the silence but there was no need to blame the US media in the first place. Silence in the first place would have been fine for the Kremlin.
"The point is, the U.S. was pulled into war by Japan and did not have had any obligation to lose even one more person to end the conflict."
The US wasn't pulled into war by Japanese children, though, and you seem to be perfectly fine with their extermination under your perverse doctrine of collective guilt. "No one is arguing this. But when it comes to the life of my son or brother vs. the life of someone I don't know, I know what my choice will be every single time. And I would bet my entire net worth that 999 out of 1,000 people would choose similarly in that situation. The instinct to stay alive completely outstrips armchair intellectualism and 20/20 hindsight"
People decide to do lots of shitty things for all sorts of reasons. The mere act of deciding to do said shitty thing and the fact that that shitty thing is a popular choice doesn't make it less shitty and doesn't serve as a moral justification. "How could President Truman possibly morally justify telling Americans that even one more of their sons had to die in order to protect enemy civilians?"
Just because the general public would find it difficult to put moral worth into civilian lives of an enemy doesn't make those lives worthless.
