Is the purpose actually to cover up intentional sabotage by an anti-China entity?
I don't know, but it entirely plausible when you consider the long history of lies by the entity that is most anti-China. Especially since it has a $1.6 billion budget specifically for anti-China propaganda
Interesting way of saying, "...in which Japan savagely attacked China and just about everywhere else in the region, and as far away as Pearl Harbor."
But we mustn't be mean to our allies right? Nanjing was only a little massacre and they are already pissed off at us because our military personnel keep raping their women.
