Well, whether or not Hiroshima and Nagasaki were atrocities are up for debate. I fervently disagree with it... But that probably isn't a road to go down.
I will say that the Japanese, Italian, German, and Japanese (not twice on accident) would be a much better choice. Of course it was mentioned in INVADERS, but not delved into as much as it may have been if written now.
What I have to say that relates to this comic is that back in Captain America HEROES REBORN, that was the exact reason he was put out of commission.
I wonder if that is where Austen got the idea.
I wouldn’t be surprised. But I did appreciate Austen’s interpretation a lot more.
