Wow... er...
The animation would have been pretty good, if you had actually included some people. Also, the entire storyline is completely illogical. WHY would China invade North Korea? That makes no sense. If anything, China + North Korea would invade South Korea.
And China, though they have been pretty ambitious in the past, would never do something as rash and impulsive as nuking NYC. And how, after flying only 30 seconds over Chinese airspace, were they suddenly over France, and then all of the sudden over the Atlantic?
And WHY would the United States nuke Hong Kong of all places? Hong Kong is trying to gain independence from China. If the US was going to nuke a big Asian city for the heck of it, it would be Beijing or Tianjin or Shanghai or Chongqing or something.
Just...grossly uninformed... :(
