G.I. JOE stands for (in the new movie):
Global Integrated Joint Operating Entity

He's not even American, lol.

Not that that even matters, because this movie will suck, officially. It will bomb in the box office, it will suck arse, and will ruin GI JOE forever. Then they'll make a sequel which will be slightly better, but still crap.
I know man, it's just really unfortunate that there doing that to the best toys/ tv show ever made!
