The thing that I liked most about this show is that the patriot citizens were willing to stand up to the corrupt, illegitimate government. That is a brave and very hard thing to do.
The following are possible parallels to current events:
A private corporation owning/creating a country - reference to corporate power and influence in the U.S. government. This is probable a reference to the mega mercenary company Blackwater an/or Halliburton. Both companies are making big money in the Iraq and Afghanistan wars.
Gray Anderson said, "This convention is a sham. And when it's done I don't think there's anything this government is not going to have the power to do in the name of national security." - reference What George Bush and Dick Chaney has been doing to this country for the last 8 years.
The "patriots" in this show are the citizens standing up to the corrupt, illegitimate government. Patriots in the show do not obey their government blindly. The citizens are the government.
I know this is obvious; September attacks - reference nine eleven
