The peacekeepers were anything but UN. There were employed by Panem, and they were doing the very non-Kofi Anon approved deed of hosing down the race rioters in the predominately black district. The lady who wrote the book may have been an Air Force brat Catholic, but she said she got the inspiration one night when she saw a new report of troops in Iraq followed by game show. Hence the analogy of rightwing patriotism and sending troops to Iraq with gameshow exploitation. The leftist American Library Association heartily endorsed her books. I doubt that was because they wanted the young skulls full of mush exposed to a states rights theme. Instead I think it’s because they saw the fairly overt theme of resistance to class exploitation.
Sorry, I didn’t get one hint of “class” but TOTAL resistance to government.
