The phrase "new world order" has been in use at least since the aftermath of the first world war gave rise to the League of Nations, and post-WWII agreements formed the United Nations. After the first Gulf War President George H. Bush used the phrase in a speech lauding the expulsion of Iraq from Kuwait.
What these 20th century new world orders represented however seemed to be neither new nor worldwide. While the maps were redrawn the world remained divided between east and west; between nations based on freedom and democracy (in politics and economy) and those not so. Even as the crashing surf changes the beach - it's still sand and water in the morning.
But what has, or is in the process of emerging in the wake of the recent global financial crisis seems to be genuinely something new; something genuinely worldwide in scope; and something which will order every life.
