I get her idea, Russia is actually in China's grip. Though I wonder where she got a verifiable Chinese GDP and population number ( I sure hope she didn't copy the WTO numbers)
Geopolitics

geopolitics (jē″ō-pŏl′ĭ-tĭks) noun
The study of the relationship among politics and geography, demography, and economics, especially with respect to the foreign policy of a nation.
Her analysis is very flat in that regard also because the USSR had sattelite states, but in general I think it is useful in the sense that it underlines that the US is no longer ahead of China. Her other articles on the topic are similar to the FA article. She doesn't go into the details but the structure of the task the military of China and US seeks to fill is different: China has to fight US, US protects water ways, helps defend Europe, etc. which is a big factor in the military strategic balance between the two.

Yes thanks I scanned that link, when you posted those later. I did find her work and methodology insightful. Especially her historical reference and creating a sort of Superpower Index. She uses references that to me aren't always understandable. Like how to measure or guessimate GDP in the 19th century. But since her work was peercheked I assume her method should check out.
