I'm classing it as a certainty. Have a read of the Wolfowitz Doctrine and work out what it necessitates, and that to be done very soon.
Even so, I believe the US has 'missed the bus'. It needed to have initiated vigorous conflict earlier this year to be sure of victory in that coming war. It can't start anything worthwhile now until at least the next Spring-Summer campaign season. By then China will have had another 12 months of growth, and the US another 12 months of decline.
