AHC: Have other countries have a GDP of $10 trillion or above by 2015

EXCEPT China and/or India. For GDP, we will be using the nominal measurements, which tend to be more reliable.

Supranational unions are excluded also, so the EU is not a valid choice

The only country I can think of capable of pulling this off is Japan, if it manages to avoid the Lost Decade, ensure stable enough economic growth, and either raise their population by domestic means or immigration
 
Apart from Japan, the usual suspects of Russia, Brazil and Indonesia could be used.

Russia could have reformed its economy successful during the Communist era and dealt with its population decline issues. Indonesia could copy Singapore on a grand scale, and Brazil could go through a period of political stability and a commodities boom. The POD's would probably have to be around 1960.

I would say Indonesia is probably the least likely of the three to obtain this. Brazil and Russia are commodities based countries so you would need the equivalent of a fast growing China to help these countries grow, maybe they profit from Japan's growth from the 1960s-80s.

BTW China already had a nominal GDP of $10 trillion in OTL.

India drops to 7th or 9th in the world by nominal GDP, so you need a big POD like the other countries to change this.
 
German Empire wins WWI with Brest-Litovsk+September Programme gains, and without total economic collapse and a second world war and alienating much of the Jewish scientists of the Empire, they develop nuclear weapons in the late thirties or forties, and are basically set in stone as the continental hegemon from there on out. Biggest risk is that the Social Democrats get a bit too antsy for the Junkers' liking, and they decide another engineered crisis+world war is the way to clamp down on it, like last time.
 
Easy-peasy.

You didn't specify WHICH dollar. By 2009, Zimbabwe was printing 100 Trillion dollar notes, hyperinflation had gotten so bad. So EVERY country in the world had a GDP greater than that.
 
The First World War was the "system accident," or the "perfect storm" if you will.

WWII was actually easier to prevent even though it was the more terrible of the two.

This challenge is heavily population dependent. Any country with a population around half that of the United States would require almost same per capita GDP as the United States. Russia and Japan are the only countries remotely capable of achieving that. A country with the borders of the Russian Empire or Soviet Union would have the easiest shot of achieving it. In fact, with a required GDP of $10 trillion and a current United States GDP of around $17 trillion, it would only require the Soviet Union to maintain its same economic size relative to the United States that the country had in the 1980s.
