Im gonna put a very decent alternitive here, one that would probably, without looking at the tracks shedule for the remainder of 2010, fit in better than Magney Cours. Fuji in Japan is up to spec, and whilst the cars are out in Japan, give them a second race, call it the Pacific GP or something else.
Or if you are wanting a track thats in Europe thats up to spec, and will be popular to go back to, Imola. The only problem is that if you take out the cars and teams to Singapore and Japan, it would make better sence to have a race out that way from a Logistical point of view.
I think the Korean War is a good while away, but you never know how fast something could happen in such a volitile region of the world.
