SC, The world could benefit from a much more assertive Russia and China, along with the other BRIC nations, if just as a check/balance on the crazed lunatics who are running US/Europe. Putin is coming back in Russia, and China gave the US an ultimatum over meddling in Pakistan, so that was at least a start.
The concept of a 'unipolar world' (one superpower, the US) has been a disaster for the world, with a much bigger disaster coming. The world, and the West itself, is being run into the ground by its lunatic financier class. These parasites won't be happy until the entire world is reduced to abject poverty, and they brag about wanting to reduce world population down to 1 billion people, for the good of 'the planet'. They long to get rid of us useless carbon dioxide producing humans, making the job of running their emerging prison planet that much easier.
