Metatron-
Well, didn't the Book of Daniel prophecy this to begin with?
In the last days there would be no 'one' world power because the UN would obtain authority from these nations to carry out its attack on Babylon the Great.
The Anglo-American power would HAVE to give up influence and authority for this to happen.
You stated that 'in 10 years' or so China would become the next world power. This won't happen because the Bible does not mention a world power existing after the UN.
It should make you think then how close we are to the beginning of the Great Tribulation.
