Recent years there's been talk of a new multipolar world order to replace the current US dominated one. With increasing economic and military power in India, China, Brazil and other states the reasoning goes that no one state will be able to dominate world affairs are readily as the US apparently can or could in the recent past. Allowing that one or other or all of these powers do sometime in the next 50 years or so actually get to world power status do you think this will be a net good for the world or otherwise?
