Who do you think will be the next superpower? of course apart from USA?

China will be the next political, economic and military superpower.

It will be Japan next, then China and India will be close.

It is DPRKs(North Korea) fault, and indirectly China's. China pulled the strings for North Korea's actions that have convinced the Japan to ramp up their own JDF, and most of the world is approving, except a couple who really don't want Japan to develop a better Nuclear Weapon. Too bad China, You Knew what Japan was capable of when you started this.

The BRIC countries will continue to be attractive to investors, but Brazil and Russia are just too corrupt, and their players too unpredictable.

China

You said it already...thats pretty much it.

The coming century will see a power struggle between the Old World of Europe and America losing their power and dominace to the Majority World. You gotta remember folks, we're less then a quater of the worlds population, and we run the show. Our time is coming to an end, its inevitable

Neither...I think the US will remain the world's most superpower until the end of the world.

China and India are the best choices

Out of those choices I would say China.

France and Canada

Korea

Russia

China

China and the European Union.
