The reason why the Nuremberg and Tokyo trials were held is because the world wanted to punish Germany and Japan for their atrocities during World War II--and wanted to show the world that such actions in the future would not be tolerated
I'm just guessing from my observations from the book. I only read it once and it was a long time ago. I think the answer would be no. I think what the novel reveal about real enemies is anybody who comes into power and uses that power selfishly. But if you want a better answer I suggest you go on Sparknotes.
The incorrect usage of the singular possessive is found in the following option:
A. Icarus's fate was sealed when he approached the sun.
The problem is that it should be "Icarus' " - if the word ends with "s", you just add the apostrophe, not an additional S. (actually this is disputed, but it's the only problematic option among the options given)
Thesis Statement. Hope this helps :)
