Just watched these two videos today. Both concern the US as a leading superpower, but both presenters are of different opinions about the chances of US continuing to be a leading power.
The presentation above given by Robert Guest is a Washington correspondent for The Economist. This presentation is funny at times, but it's center argument does not quite convince me as much as Hans Rosling's presentation, which is equally funny presentation.
This could well be because I just love numbers and the numbers Hans Rosling presents so clearly demonstrate the connection and plausibility.
