B.t.w., here's the article, but we should still be wary of the statistics, one of them is in current prices while the other is in p.p.p.
Furthermore, i'm not sure that the g.d.p. is the best way to estimate the economic power of a state, there may be biases if, e.g., a capitalist economy leads to an artificial augmentation through the different capitalistic rents, i.d.k.
Even by these standards, the u.s.s.r. did better than the ex-colonies (source) and most of the world , despite having a more democratic workplace, better working conditions, sanctions, ..., and military is such a waste of money while we could unite, and use this money for so much more.
I've seen that germans are quite active here, as well as on reddit, frenchs only arrive third as non-english speakers, it's a bit weird not to hear more about Spain&Portugal or Italy, 🤷‍♂️
I'd say that i'm french but i.d.k. if i'm entirely identifying with my country anymore, what's certain is that i'm identifying with the classic(pre-XIXth) authors of western Europe, may i ask why you were happy that Berlin had to be excluded :) ?
