Not only was it laughably unrealistic, with a stupid scenario that made no sense, but it's just a tea-party bukakefest of US nationalism.
It was basically just "MURICA! FOOTBALL, M16'S, WHITE PEOPLE, USMC!!, MUSCLECARS, AND FUCK YELLOWSKINNED ASIANS, THEY SUCK AT DRIVING, AND ARE TOO GOOD AT MATH AND PLAYING FRUITY MUSICAL INSTRUMENTS!"
and then.. North Korea? Really? Lol...
They should have just made it like... Latin America invaded us Risk-Style... Hugo Chavez traded a fuckton of oil to Russia and China for weapons and planes, united all of latin america, renamed it 'mecksiko' and invaded the USA with a ton of brown people speaking mecksican while smoking fat doobies they got by stealing jobs from white people.
