I noticed a lot of the flags of the so-called "American Empire" posted up just look like variations on the existing flag. I decided to go for something that would stand out a bit more.
I made this to highlight the rampant exceptionalism and eagerness to go to war that most Americans seem to have these days.
I don't know why, but this also gave me the idea for this weird setting. You don't have to associate with this flag or vice versa, but it's just an idea I had for a setting with an American monarchy:
"Following the attacks on the Two Towers in the New York province of the American Empire, King George Bush II, at the behest of his subordinate Viceroy Dick Cheney, declared war on the Kingdom of Persia and issued a royal decree, giving the Royal Guards of the American Empire near-unlimited powers to spy on and arrest citizens on suspicion of them being traitors to the Empire."
Please do not use this without my permission.
UPDATE: I've posted a newer version, at a higher resolution, and it also has none of what I call "pixeljunk", as in the edges are sharper, and none of the blurriness and poor quality.
UPDATE 2 (8/12/14): I have come around, bowed to public opinion, and changed the name so that it is no longer redundant.
However, there were powers opposed to the dictatorial American Empire: the Tsardom of Russia, ruled by Tsar Vladimir III, the People's Imperial Republic of China, the Union of Arab Jamahiriyas and the Divine People's Empire of Greatest Chosun of the North under the Kim dynasty.
